Abstract:Taking sci-tech entrepreneurship services in Xizang as the study object,this study has systematically analyzed their current development status,specific demands and pathways for system optimization.Currently,poli-cy-driven initiatives have yielded phased achievements,evidenced by the rapid growth in the number of technology-based enterprises,continuous improvement in entrepreneurial platforms and carriers,and effective implementation of initiatives such as innovation vouchers.However,Based on the comprehensive analysis on existing researches,policy evaluation and field observation,this study has identified several prominent systemic bottlenecks in the cur-rent service framework,including"last-mile"obstacles in policy transmission,homogeneous and professionally in-adequate service provision,alongside prominent challenges such as widespread financing difficulties,shortage of high-end talents and inefficient commercialization of sci-tech achievements faced by enterprises.In response to these challenges,this paper has further identified the specific demands in terms of distinctive industry incubation,culturally adaptive services,diversified financial support,targeted policy coordination,and high-end talent introduc-tion and cultivation.Accordingly,it has proposed systematic strategies focusing on policy mechanism optimization,service platform construction,talent introduction and cultivation,sci-tech finance innovation and regional coordinat-ed development to establish a modern sci-tech entrepreneurship service system aligned with plateau characteristics,providing insights for innovation-driven development in Xizang.

Abstract:Severe forage shortage during the cold season in Shigatse,Xizang had formed constraint on the sustain-able development of local animal husbandry.To screen high-yielding and supreme Avena sativa L.varieties suitable for high-altitude environments,a field introduction trial was conducted on 5 oat varieties in Saga county,Shigatse.Agronomic traits,biomass structure and forage yield were measured at the flowering stage.The results revealed highly significant differences(P<0.01)among varieties in agronomic traits such as plant height,stem diameter,tiller number and distribution ratio of dry matter in stems,leaves and panicles.QY2 exhibited optimal performance in plant height(112.15 cm),stem diameter(4.13 mm)and fresh forage yield(16,766.82 kg·ha⁻²),while QY3 achieved the highest hay yield(5,695.12 kg·ha⁻²),with the distribution rate of panicle dry matter at 35.63%,indicating out-standing dry matter conversion rate.Random forest analysis identified fresh forage yield,variety type and effective tiller number as the primary factors influencing hay yield.The TOPSIS comprehensive evaluation demonstrated that QY2 and QY3 exhibited the best overall performance,making them suitable as primary recommended varieties for high-altitude areas such as Shigatse and southern Xizang,providing varietal support for local cultivated forage pro-duction and animal husbandry development.

Abstract:Objective This study aimed to investigate the clinical efficacy and safety of Aruse purgation therapy,a type of Tibetan medicine combined with pumpkin seeds and areca nuts in the treatment of 48 patients with intestinal taeniasis.Methods A self-controlled before-and-after study design was adopted,in which 48 patients with intestinal taeniasis received the Tibetan medical anthelmintic therapy to observe its clinical efficacy and safety.Results After treatment,the patients'symptoms such as abdominal distension,anorexia,discovery of white proglottides in under-wear/bedding/feces and anal itching significantly improved compared to those before treatment,with statistically significant differences(P<0.001).Paired T-test analysis on renal function,liver function and CBC(complete blood count)before and after treatment showed no significant differences(P>0.05).Conclusion Tibetan medicine has an early understanding of intestinal taeniasis and a rich theoretical foundation.Aruse purgation therapy demonstrates significant efficacy in intestinal taeniasis treatment and shows no side effects on patients'renal function,liver func-tion or CBC,revealing a high level of safety with no significant side effects.

Abstract:As an ancient,endemic tree species on the Tibetan Plateau,Hippophae spp.serves not only as a pioneer species for the ecological restoration in the middle reaches of the Yarlung Zangbo River basin,but is also a signifi-cant biological vehicle for implementing the four key priorities-stability,development,ecology and borderland prosperity in Xizang in the new era.Under the strategic background of the"Four Initiatives"advancement in Xizang Autonomous Region,the major challenge lies in how to transform the biological advantages of Hippophae spp.into drivers for high-quality regional economic development and strategic assets for national defense security.This study has firstly identified the persistent challenge of"insufficient baseline knowledge"regarding Hippophae spp.resourc-es in Xizang.Fundamental information on their spatial distribution,reserves and suitable habitats remains poorly de-fined,constituting a bottleneck that constrains scientific planning and sustainable development of the industry across the region.Secondly,although Hippophae spp.resources in Xizang offer clear advantages for tourism development,nutritional functions,cultural value and national strategy serving,the industrialization still remains at a primary stage.The sector faces multiple challenges including extensive resource utilization,limited industrial scale and mod-est economic returns.To address these issues,this study has proposed a dual strategy driven by"technology empow-erment"and"brand leadership"as a critical pathway for the sustainable utilization of Hippophae spp.resources in Xizang.In terms of technology,it is recommended to build a systematic framework of"precise general survey—dy-namic monitoring—potential assessment"to resolve problems regarding insufficient baseline knowledge,undefined dynamics and unclear potential.In parallel,the research should elucidate the unique nutritional functions of Hip-pophae spp.in Xizang and develop technologies for deep processing and maximal utilization.Referring to indus-tries,deep-processing industries and premium brands that are high-value-added should be developed upon techno-logical achievements to facilitate a shift from raw-material export to value-addition,ultimately achieving the sustain-able utilization of Hippophae spp.resources in Xizang and promoting the deep integration between ecological con-servation and industrial development.

Abstract:Alpine wetlands are critical zones for biodiversity conservation and plant resource reservoirs on the Qin-ghai-Xizang Plateau.However,a lack of baseline data hindered the accurate assessment of their ecological func-tions.The Naruo National Key Wetland,a typical glacial-lake-marsh complex ecosystem in the source region of the Nujiang River,has not yet been systematically investigated in terms of its flora.In this study,a systematic survey of wild plant resources in the wetland was conducted using a combination of line transect and quadrat methods.The re-sults revealed that a total of 406 species of wild vascular plants,belonging to 183 genera and 52 families were docu-mented.The flora exhibited significant temperate characteristics,with temperate elements accounting for 96.75%and 60.00%,respectively.The wetland hosted a variety of important resource plants,and 16 rare and protected wild vascular plant species were discovered.This study has clarified the plant resource baseline of Naruo wetland for the first time,filling the gap in the systematic survey data for this region,providing solid scientific basis for the sustain-able conservation and biodiversity management of the wetland.

Abstract:Based on the disaster record and hourly precipitation data from meteorological stations along the Xizang Segment of the Sichuan-Xizang Railway from May to October between 2007 and 2019,this paper has studied the characteristics of main geological disasters and precipitation distribution along the railway.It is found that:(1)Main geological disasters along the Xizang Segment of the Sichuan-Xizang Railway were landslides and debris flows,with debris flows occuring in Shannan,Linzhi and Changdu,while landslides concentrating in the Linzhi and Changdu segments,which featured steep terrain and prolonged precipitation,predominantly during the main flood season in July and August(2)Precipitation along the Xizang Segment of the Sichuan-Xizang Railway mainly oc-cured between 22:00 and 06:00 in July and August,which should be avoided by the railway operation;(3)Extreme hourly precipitation thresholds along the Xizang Segment of the Sichuan-Xizang Railway were generally above 5mm except Bomi,Basu and Jiazha,among which Gongga and Lhasa have reached 7.8mm and 7.3mm,respective-ly.The railway operation needs to pay attention to the convective weather in Lhasa,central Shannan and eastern Changdu,as well as the impact of continuous precipitation in Linzhi,southern Changdu and eastern Shannan.

Abstract:To follow the concept of"Lucid waters and lush mountains are invaluable assets",to promote the con-struction of Xizang as the ecological security barrier and the"integration of green development and prosperity",this paper takes the large-scale planting of Armeniaca sibirica forests in the Lhasa North-South Mountain Greening Proj-ect as the research subject to expore the paths for realizing ecological product value.It is found that the project has succesfully achived large-scale planting of Armeniaca sibirica and yieled siginificant ecological benefits.However,the exploration of economic value still remains in infancy,and their ecological advantages have not yet been fully transformed into livlihood benefits.Based on the theory of ecological resource capitalization,a diversified and inte-grated value realization path system of"planting-processing-marketing-tourism-carbon"has been constructed,spe-cifically including:consolidating the foundation of standardized planting;extending the deep processing industry chain for high-value-added products;promoting the deep integration of"Armeniaca sibirica plus"with cultural tour-ism;developing new rights and benefits of forestry carbon sinks and ecological compensation;strengthening the col-laborative support of policies,finance and taxation,which aims to achieve the transformation of Armeniaca sibirica forests from single ecological function to a multiple value system of"ecological improvement,economic efficiency and livelihood enhancement",providing theoretical basis and practical reference for the ecological protection and green prosperity on the Tibetan Plateau.

Abstract:Based on the meteorological data from Shigatse Meteorological Service from 1990 to 2024,along with crop growth period observation data from the provincial agricultural-meteorological observatory in Shigatse during the same period,this study takes spring wheat in Shigatse from 1990 to 2024 as the research object to clarify the re-sponse patterns of spring wheat during the growth season to heat changes in alpine regions,which has also analyzed its growth season characteristics,heat resource dynamics and their correlation,as well as the abrupt variation charac-teristics of accumulated temperature.The results show that:1)Referring to growth season characteristics of spring wheat,the full growth period was mainly concentrated from April to September(averaging 142 d),showing a signifi-cant shortening trend from 1990 to 2024(decreasing by 0.75 d/a,P<0.01),dropping from nearly 170 d in 1992 to ap-proximately 130 d in 2024.The sowing-jointing(0.39 d/a)stage was significantly shortened.The heading-maturity(0.33 d/a)stage also exhibited a shortening trend,though it failed to pass the significance test,indicating a relatively weaker effect.The milk ripening/maturity stage was the most temporally concentrated(δ=3.7/3.6),and the tillering stage showed the largest dispersion(δ=11.1).Referring to heat dynamics,the average temperature during the growth season increased significantly(0.43℃/10a,P<0.001),with an increase of 1.38℃over 32 years.The four types of ac-cumulated temperature all showed stepwise increase,with an increase from 372.5℃(≥0℃)to 816.9℃(≥15℃)from 2020 to 2024 compared with 1990 to 1999.Referring to heat impact,the heat indicators and growth period days showed a correlation pattern of"negative-positive-positive-strong negative-neutral-negative-negative-strong negative".The accumulated temperature exceeding 10℃dominated the jointing/heading stage(r=-0.542/-0.497),while the average temperature and accumulated temperature exceeding 0℃/5℃dominated the maturity stage(r=-0.687).The accumulated temperature distribution adapted to physiological needs,and there was a reverse rela-tionship that"period shortens as temperature increases"between the heat and growth stages.Referring to abrupt vari-ation of accumulated temperature,it showed that the accumulated temperature exceeding 0℃,5℃,10℃and 15℃experienced increase and abrupt variation around 2000,2005,2010,and 2010 respectively.

Abstract:Alpine grasslands on the Tibetan Plateau serve as a critical carrier for the establishment of regional eco-logical security barriers and national ecological civilization hubs,and play a vital role in the global carbon cycle.Over the past two decades,ecological restoration initiatives involving large-scale fencing and grazing exclusion have been implemented across the region to mitigate grassland degradation.However,the spatiotemporal variation patterns and optimization pathways of carbon sink effect resulting from long-term grazing exclusion remain unclear.This study has systematically integrated and analyzed 246 paired cases of grazing exclusion and grazing restoration on the Tibetan Plateau,using multi-scale methods such as field plot observation to elucidate the temporal characteris-tics and regulatory mechanisms of the carbon sink capacity under fencing and grazing exclusion.The results demon-strate that fencing and grazing exclusion have substantially enhanced the carbon sink capacity of alpine grasslands,yielding an average increase of 49%.However,the carbon sink effect exhibits marked non-linear characteristics,peaking approximately five years after implementation of the ecological projects,after which the carbon sink rate gain declines,suggesting the existence of an"optimal carbon sink window".Long-term grazing exclusion results in the excessive accumulation of plant litter,which leads to shading effect and nutrient cycling imbalance,constituting the primary factors behind the decline in carbon sink gain.This finding challenges the traditional notion that"longer duration of ecological restoration projects yields better results"and proposes the existence of a"carbon sink inhibi-tion threshold".Specifically,when litter layer thickness or shading intensity exceeds the ecological carrying capaci-ty,the carbon sink transits from an"incremental"to a"stock"model.The existing ecological project management paradigm urgently requires a shift from a static"long-term grazing exclusion"model to a dynamic and adaptive"pe-riodic rotational grazing"strategy to ensure targeted implementation of ecological projects and sustained enhance-ment of carbon sink capacity on the Tibetan Plateau.

Abstract:The Manasarovar wetland is a typical representative of alpine lake wetlands in China and has been in-cluded into List of Wetlands of International Importance in China and List of National Nature Reserves of China This paper begins with an overview and value assessment of the Manasarovar wetland,identifying its characteristics as bearing exemplary and diverse wetland functions,rare and unique wetland biodiversity,exquisite and beautiful wetland landscapes,and distinctive geothermal features.Based on the current status and existing issues in the Ma-nasarovar wetland conservation,the paper has analyzed long-term conservation strategies,recommending focusing on three key aspects:consolidating wetland conservation achievements,enhancing dynamic wetland monitoring,and intensifying wetland landscape restoration.Lastly,it explores sustainable utilization approaches for the Manasar-ovar wetland resources,advocating for a close integration with the cultural service value attributes of the wetland to establish a green industry system centered around the eco-tourism and recreation in highland wetlands.

Abstract:Soil acidification in China has become increasingly severe,with aluminum toxicity emerging as a prima-ry factor limiting crop growth.Addressing the limitations of traditional soil amendment,which are costly and prone to compaction,this study explored the ameliorative effect of plateau yak dung biochar on aluminum-stressed soil.A pot experiment was conducted under interactive treatment of different biochar application rate(0%,3%and 5%)and aluminum stress(4 mmol·L-¹).The results indicated that aluminum stress(Al)significantly inhibited the growth of Trifolium repens and reduced its biomass(P<0.05).Biochar application,particularly at 5%rate(5%BC+Al),effec-tively increased soil pH and improved soil structure,thereby significantly alleviating aluminum toxicity and promot-ing the recovery of Trifolium repens growth.Correlation analysis revealed that exchangeable aluminum was signifi-cantly negatively correlated with soil pH,root length and plant height(P<0.05),while root length and plant height exhibited a highly significant positive correlation(P<0.001).This study confirmed that the high-value utilization of yak dung from the Tibetan Plateau to produce biochar could mitigate aluminum toxicity by increasing soil pH and reducing exchangeable aluminum,offering an economically effective technical approach and theoretical basis for the remediation of acidic and aluminum-contaminated soil.

Abstract:With the intensification of climate change and increase in catastrophic climate events,animal husbandry on the Qinghai-Xizang Plateau is situated at the core of a"complex of contradiction"involving"climate change,ecological environmental protection,livelihood and sustainable development of local residents".This paper compre-hensively reviewed researches on the animal husbandry vulnerability and adaptation on the Qinghai-Xizang Plateau under climate change from the perspectives of the unique sensitivity and typicality of the plateau in the context of climate change,its impact on grassland ecosystem,its comprehensive impact on livestock carrying capacity and pas-toral economy,and extreme climate events and animal husbandry.The results show that:on the one hand,as this re-gion is an important ecologically vulnerable area in China,ecological barriers,water conservation,wetland protec-tion,biodiversity conservation and ecological security are its main functions and prerequisites.Therefore,appropri-ate animal husbandry development and its vulnerability reduction is an important strategy for the sustainable devel-opment of animal husbandry on the Qinghai-Xizang Plateau.On the other hand,as it is a sensitive and vulnerable ar-ea to global climate change,the risks associated with climate change and the region's vulnerability and uncertainty under future climate scenarios are intensifying,posing greater threats and challenges to ecological environmental protection.This study holds strong practical guidance and utility value for the development of strategies for live-stock to adapt to climate change,ensure ecological security and guide the sustainable development of animal hus-bandry sector on the Qinghai-Xizang Plateau.

Abstract:Under the influence of global climate change and human activities,the pattern and quality of forage re-sources in Qinghai Province and Xizang Autonomous Region have undergone significant changes,thereby impact-ing the spatiotemporal distribution pattern of livestock yield.Based on livestock product and forage yield data,this study has analyzed the output and per capita consumption of beef,mutton and dairy products in Qinghai and Xizang,as well as relevant county-level data in both regions.An in-depth analysis on the spatiotemporal pattern in livestock products in Qinghai and Xizang was conducted and their influencing factors were identified.The results showed:(1)Temporally,beef output experienced an initially slight decline followed by a significant rise,and mutton and dairy product output exhibited linear growth in Qinghai,whereas beef output experienced overall linear growth,dairy product output exhibited exponential growth,and mutton output showed an initial rise followed by a decline in Xi-zang.In 2022,per capita consumption of beef in Xizang(93.64kg)far exceeded that of national average(7kg),and per capita consumption of dairy products there(233.95kg)surpassed both that of national average(42kg)and global average.(2)Spatially,beef output displayed low volume in the central part and high volume in the northeast and southwest,mutton output showed gradual growth from the southwest to northeast,and dairy product output exhibit-ed gradual increase from the northwest to southeast in Qinghai,whereas beef predominated in the east and mutton predominated in the west in Xizang.In conclusion,beef and dairy product output exhibited a rise in most counties of both regions,while mutton output exhibited a decline.(3)With an increase in the average county-level forage yield,county-level beef and dairy product output showed a significant rise,while county-level mutton output experienced no significant changes in Qinghai,whereas that of Xizang showed a significant decline.In contrast,with an increase in total county-level forage yield,dairy product output showed a significant rise in Qinghai,whereas beef,mutton and dairy product output all showed significant rises in Xizang.This study provides valuable insight for decision-making in livestock product industry and offers a scientific basis for the sustainable development in animal husband-ry on the Qinghai-Xizang Plateau.

Abstract:Alpine grasslands represent a typical ecosystem on the Qinghai-Xizang Plateau and play a crucial role in China's ecological security,as well as production and livelihood of local herders and farmers.Grassland desertifica-tion is one of the most severe ecological issues in this region.Current ecological restoration measures for alpine de-sertified grasslands often face challenges such as monotonous species composition and prolonged restoration peri-ods,hindering the effective recovery of their ecological and productive functions.Therefore,exploring efficient res-toration models and innovative technologies is essential for the ecological restoration of alpine desertified grass-lands.Based on the long-term research and practical experiences in ecological restoration of alpine desertified grass-lands conducted by our team,this paper proposes a composite management model using living oat sand barriers combined with grass and shrubs.Taking typical alpine desertified grasslands as the case study,the paper elaborates on three key aspects:selection of suitable plant varieties,technical innovation in oat sand barrier implementation,as well as functions and roles of oat sand barriers,thus providing scientific reference for the artificial restoration of al-pine desertified grasslands.

Abstract:In recent years,clean energy has developed rapidly in Xizang.Currently,the region has achieved self-sufficiency in clean energy power supply,but diversified consumption pathways for surplus energy apart from out-ward transportation are still required.Hydrogen,as a clean,zero-carbon,flexible and efficient secondary energy source,is an important type of green fuel for the future.Under the"Dual Carbon"goal in China,the annual demand for hydrogen is expected to reach 130 million tons,and the scale of hydrogen production from renewable energy(green hydrogen)is expected to reach 100 million tons by 2060.Utilizing clean energy such as hydropower to pro-duce green hydrogen and creating a green and carbon-free industry chain of hydrogen is a new opportunity for ener-gy development which is highly promising.Germany and Nepal have already formulated their own hydrogen strate-gies,and China has also established a long-term development plan for hydrogen energy industry.The eastern part of Xizang(East Xizang)is rich in water resources with dense river networks and accelerating hydropower develop-ment,which will provide more clean energy power.In the future,promoting the production of hydrogen from low-cost clean energy sources such as hydropower in East Xizang,and building energy bases and supporting facilities covering the lower reaches of Yarlung Zangbo River to Jinsha River in West Sichuan will not only fully utilize local water resource advantages and expand pathways for clean energy power consumption,but also promote the develop-ment of plateau industries under the constraints of building an ecological civilization highland.This approach will develop a green economy with green industries,achieve high-quality and leapfrog development in East Xizang and contribute to the energy security and realization of"Dual Carbon"goal in China.

Abstract:Despite possessing a unique theoretical framework of"Three Causes and Five Sources"and abundant plateau medicine resources,Tibetan medicine currently faces critical bottlenecks in R&D(research&development),including unclear material foundation,undefined pharmacological mechanisms,and absent quality standard.This ar-ticle has systematically reviewed the opportunities and challenges of AI(artificial intelligence)in modernizing Tibet-an medicine R&D.In terms of opportunities,AI can be leveraged to construct specialized databases and knowledge graphs for Tibetan medicine,enable high-throughput screening of active ingredients and multi-target mechanism analysis,and establish intelligent systems ranging from medicinal material identification to drug quality control.The challenges,however,center on the fragmentation and non-standardization of Tibetan medicine data,semantic gap be-tween traditional theories and modern algorithms,and shortage of interdisciplinary talents.Looking ahead,only by strengthening foundational data infrastructure,developing specialized algorithm models tailored to Tibetan medical theories,and building deeply integrated interdisciplinary teams can AI fully unleash its role as the core engine to guide the Tibetan medicine industry toward high-quality and sustainable development.

Abstract:With the rapid growth in global energy consumption,the interplay among nations in reducing green-house gas emission is becoming increasingly intense.As a significant source of clean energy,photovoltaic(PV)pow-er generation play an important role in promoting regional economic development,advancing global energy transi-tion,and achieving the global goal of"carbon neutrality".The Qinghai-Xizang Plateau,characterized by fragile eco-systems and abundant solar resources,has experienced rapid development of PV power industry.These PV power plants have exerted significant impact in near-surface energy balance and microclimate,thereby altering soil nutrient cycles,as well as fauna and flora,ultimately leading to notable ecological effect.Consequently,the sustainable de-velopment of PV power plants is crucial for the rational utilization of solar and grassland resources,balancing PV in-dustry growth with ecological environment,and enhancing regional socio-economic conditions across the region.Hence,this paper has reviewed the impact and underlying mechanisms of PV power plants on ecosystem structure and functions in the Qinghai-Xizang Plateau,including local surface microclimate,soil nutrients,as well as fauna and flora traits.By comprehensively considering the ecological effect of PV power plants,an evaluation system for PV plant construction suitability is built to support regional sustainable development.

Abstract:Morphological changes in animals are closely related to their adaptation to ecological environment,which may vary depending on morphilogical functions.Bergmann's rule and Allen's rule are two classic theories that explain the interrelationship between functional morphological traits and ecological environment factors.The former posits that animals exhibit larger body size in colder environment,while the latter suggests that animals de-velop shorter tails and limbs in colder environment.To investigate the universality of these rules for ectotherms,this study took Laudakia wui distributed in the Yarlung Zangbo River basin of Xizang as the model.By assessing chang-es in the three functional morphological categories—body size,locomotion and sensory traits along altitudinal gradi-ent,Bergmann's and Allen's rules were tested,and correlations between morphological changes and climatic fac-tors were explored.Results indicated that the body size of Laudakia wui significantly decreased with increasing alti-tude,contradicting Bergmann's rule;while forelimb traits enhanced,and tail length and eye diameter decreased with increasing altitude,partially supporting Allen's rule.Furthermore,net primary productivity was significantly positively correlated with snout-vent length,head characteristics and tail length.This study has revealed the strate-gies employed by Laudakia wui to adapt to environmental pressure through morphological changes,which offers critical insight into its potential response to climate change and holds scientific importance for biodiversity conserva-tion on the Qinghai-Xizang Plateau.
