Abstract:In the stage of improving the quality of the existing urban stock during China's urbanization process,the renewal design of old-city riverside greenways has become a crucial aspect of urban development.This paper focuses on the design of riverside greenways from the perspective of old-city renewal,analyzes the dilemmas in their renewal,such as spatial structural imbalance,lack of cultural gene decoding,and mismatches between functional supply and demand.Taking the Tonghui River Greenway in Meishan as an example,it examines the difficulties in its renewal,including spatial fragmentation,cultural disconnection,and functional mismatches.By introducing the theory of spatial justice,a trinity design strategy of'spatial patching-cultural decoding-functional coupling'is proposed.Through practical implementation,in terms of spatial patching,it is required to create a continuous and smooth walking experience,repair fragmented spaces,and achieve the integrity of the greenway system.At the cultural decoding level,cultural repair and cultural implantation strategies are adopted to reshape cultural memories.In the dimension of functional coupling,consumption scenarios are arranged in combination with regional cultures and the needs of citizens to realize the organic integration of functions and demands.This case provides replicable strategies for the organic renewal of old-city riverside areas in the era of existing stock,promotes the transformation of'functional greenways' into'warm urban life belts',enriches the theoretical research on the design of riverside greenways in urban renewal,and offers practical references for other regions.Meanwhile,it provides new ideas for the research on the organic renewal of old-city riverside greenways,thus having important theoretical and practical significance.

Abstract:The golden snub-nosed monkey is a species with a one-male-multi-female layered social structure,exhibiting complex and diverse social behaviours.A hand-reared infant monkey can acquire essential social behaviours via reintroduction into a population of conspecies.However,studies on reintegrating a hand-rared golden snub-nosed monkey under captive conditions are still lacking.Our study focused on reintroducing a hand-reared golden snub-nosed monkey into a social group.Using instantaneous and scan sampling,the frequency and changes of social behaviours,such as carrying,grooming,holding,sitting closely,aggression,and play,exhibited by different individuals in the group towards the reintroduced infant,were observed.The data revealed that the group members successfully established social relationships with the introduced infant(IF).The biological mother of IF(AF1)exhibited the highest frequency of carrying,sitting closely,and holding,followed by a subadult female monkey.SF primarily play with IF,whereas no distinct interactions between adult males(AM)and IF were observed.These findings highlight the necessity of establishing a group structure similar to wild golden snub-nosed monkeys to facilitate the reintegration of hand-reared individuals.This study provides valuable insights and theoretical guidance for the reintegration of hand-reared primates.

Abstract:This study provides a basis for effective bird strike prevention by offering a comprehensive understanding of avian community structure,spatiotemporal distribution characteristics in the airport.From August 2023 to July 2024,bird diversity in six habitat types within Yanan Nanniwan Airport's flight zone and 6 km airspace clearance area was investigated using line transect and point transect methods,documenting 61 avian species across 13 orders and 31 families.This included 13 National Grade Ⅰ and Ⅱ Protected Species,with 30 residents,21 summer migrants,5 winter migrants,and 5 passage migrants.Phylogenetic distribution revealed 11 Oriental Realm species,36 Palearctic Realm species,and 14 cosmopolitan species.Temporal analysis indicated peak Shannon-Wiener diversity in summer(2.05)and trough in winter(1.39).Spatially,woodland habitats exhibited the highest diversity(2.66),while agricultural land showed the lowest(0.93),with annual average flight altitude concentrated below 30 m AGL.Based on these findings,seasonal target bird species for prevention,priority areas for bird strike mitigation,and tailored intervention strategies were systematically analyzed and proposed.This study provides a scientific basis for the prevention of bird strikes at airports.

Abstract:In this study,six ecological sensitivity factors were selected to assess the ecological sensitivity of Jian'ou City,including elevation,slope,aspect,NOVI,water body buffer zones,and land use types.The Analytic Hierarchy Process(AHP)was employed to determine the weights of each factor.Using ArcGIS spatial analysis tools,both single-factor and multi-factor sensitivity analyses were conducted,and the ecological sensitivity zones were classified accordingly.The results indicate that the comprehensive ecological sensitivity of Jian'ou City is predominantly concentrated in moderately and highly sensitive areas,accounting for 29.76％and 27.79％of the total area,respectively.The proportions of low,slightly,and extremely sensitive areas are 8.89％,17.11％,and 16.45％,respectively.Among the influencing factors,land use types and water body buffer zones had relatively high weights,at 0.3727 and 0.1999,respectively.Spatially,the ecological sensitivity of Jian'ou City tends to increase gradually from the southwest to the southeast.This study provides a scientific basis for the construction of ecological security patterns and urban development planning in Jian'ou City.

Abstract:To explore the effects of light and fertilization on the growth and functional traits of Ormosia hosiei seedings,and provide theoretical support for the integration of high-quality and strong seedlings cultivation and efficient cultivation techniques of O.Three years old O.:hosiei seedings were subjected to a 6-month experiment with varying light conditions(full light,50％light transmittance,30％light transmittance)and fertilization(5 g urea+5 g KH2PO4 per plant,10 g urea+10 g KH2PO4 per plant,no fertilization)The results showed that:(1)Different light and fertilizer treatments had no significant effect on the growth of ground diameter,but under 30％light transmittance,fertilization significantly increased the growth of seedling height;(2)With the increase of shading degree,the number of leaves,stem height and biomass of O.hosiei seedings decreased.Under shading conditions,fertilization increased the number of leaves,stem height and plant biomass of seedings,and the effect was most significant under 30％light transmission,but under full light conditions,fertilization did not significantly promote the plant functional properties;(3)With the increase of shading degree,the chlorophyll content,net photosynthetic rate,transpiration rate and water use efficiency of O.hosiei seedings decreased in varying degrees.Under the conditions of 50％light transmission and full light,the amount of 10g/plant fertilization significantly increased the net photosynthetic rate and transpiration rate of leaves,and also improved the water use efficiency.However,under the conditions of 30％light transmission,fertilization increased the net photosynthetic rate and transpiration rate of leaves,but decreased the water use efficiency.In conclusion,O.hosiei seedings have strong shade tolerance,and 50％light transmission conditions have no significant impact on their growth.Under 30％light transmission conditions,applying 10 g of fertilizer per plant can effectively enhance their ability to resist low light,improve the growth and photosynthetic capacity of young trees.

Abstract:[Objective]To further explore and understand the biodiversity and geographical distribution patterns of lycophyte and fern flora in the Jiaozi Mountain National Nature Reserve of Yunnan,and to furnish data support for the conservation and utilization of these plants within the reserve.[Method]Drawing on data from scientific expeditions,routine monitoring efforts,and literature reviews conducted in the Jiaozi Mountain National Nature Reserve in Yunnan,this study analyzed the species diversity of fern flora in the reserve,focusing on species composition and geographical distribution.[Result]The results indicate that the Jiaozi Mountain National Nature Reserve harbors 120 lycophytes and ferns,which belong to 15 families and 31 genera,accounting for 36.59%of the total lycophyte and fern families in China.Among these,five families—Athyriaceae,Cystopteridaceae,Dryopteridaceae,Pteridaceae,and Polypodiaceae—each contain more than five species.At the genus level,Polystichum,Dryopteris,and Adiantum exhibit the highest species diversity,while monotypic genera account for 13(41.94%of the total genera).Additionally,one provincially protected species,Neocheiropteris palmatopedata was recorded.In flora,cosmopolitan families dominate at the family level(12 families);cosmopolitan genera prevail at the genus level(12 genera);and East Asian elements prevail at the species level(62 species).

Abstract:[Objective]This study aims to systematically review the evolutionary trajectory and research trends of domestic rural courtyard landscapes,providing theoretical references for the optimization of human settlements under the Rural Revitalization Strategy.[Method]Employing bibliometric methods and the CiteSpace visualization tool,a comprehensive analysis was conducted on 521 core articles published between 2007 and 2025 in the China National Knowledge Infrastructure(CNKI)database.Technical approaches included keyword co-occurrence,cluster analysis,and burst term detection.[Result]The findings indicate that research in this field is significantly policy-driven,with its overall development trajectory aligning closely with national rural construction policy milestones,divided into three distinct stages:the germination period(2007-2013),the rapid growth period(2014-2018),and the high-level plateau period(2019-2025).In terms of spatial distribution,while research forces are concentrated in higher education institutions,inter-institutional collaboration networks remain loose.Furthermore,a significant north-south geographical differentiation is observed:southern regions focus more on ecological aesthetics,whereas northern regions prioritize practical functionality.Through keyword cluster analysis,five core research dimensions were identified:rural strategy and spatial planning,landscape ecology and sustainable development,regional culture and village renewal,human settlement optimization and social impact,and design technology and methodology systems.Evolutionary trends reveal a shift in the research paradigm from early singular landscape design practices to systematic studies covering cultural heritage,ecological resilience,and social value assessment,with"regional culture"and"digital technology"emerging as key growth points.[Conclusion]Addressing limitations such as insufficient quantitative analysis and a lack of interdisciplinary integration,this paper proposes that future research should transcend qualitative descriptions,strengthen interdisciplinary theoretical integration,deepen the application of digital technologies like artificial intelligence and big data,construct precise and intelligent evaluation systems,and improve cross-institutional collaborative networks to promote high-quality and systematic development in this field.

Abstract:In recent years,infestations of Acantholyda posticalis in Culai Mountain Forest Farm have intensified,resulting in suppressed tree growth.To effectively curb the spread of this pest and safeguard forest resources,UAV aerial control trials were carried out at the farm from 2024 to 2025.The spray mixture consisted of 10%abamectin·diflubenzuron,Tianda 2116,and aerial application adjuvant at a ratio of 100g:10g:10g.Results indicated that this UAV based program achieved excellent control efficacy against Acantholyda posticalis larvae,with population reduction rates of 94.8%in 2024 and 95.7%in 2025,representing outstanding overall control performance across the two?year period.Furthermore,UAV aerial application outperformed conventional manual spraying in operational efficiency,application precision,and cost management.Characterized by high efficiency and accuracy,it shows strong potential for large?scale pest control and provides reliable technical support for scaled?up forest pest management at the farm.

Abstract:Based on the natural geographic data,relative slope,aspect,relative distance,visual probability,relief amplitude of terrain and vegetation pattern in forest park are taken as evaluation index factors.Using AHP method to establish the weight of each index,combining with GIS technology,the evaluation system of landscape visual sensitivity of forest park is established,and the visual sensitivity of Fuzhou National Forest Park is evaluated.Using the Yaahp analytic hierarchy process(AHP)software,we established a hierarchical structure model based on judgment matrices and derived the weight values of each indicator.The calculated random consistency ratio(CR)of the judgment matrix was 0.021,which falls within the acceptable range of CR ﹤ 0.1,indicating satisfactory consistency of the matrix.The final weights assigned to the indicators were:relative distance(0.2653),vegetation pattern(0.4295),relative slope(0.1489),aspect(0.0284),terrain relief(0.0819),and visual probability(0.0460).The ranking of indicator importance was:vegetation pattern ﹥ relative distance ﹥ relative slope ﹥ terrain relief ﹥ visual probability ﹥ aspect.The results show that the visual sensitivity of Fuzhou National Forest Park is vastly different,the main influencing factor is vegetation pattern.Within the 300-meter buffer zone along the main roads of the park,landscape visual sensitivity gradually increased with distance from the roads.Beyond this 300-meter buffer zone to the park boundary,the visual sensitivity showed a gradual decline.Assessing landscape visual sensitivity objectively can instruct the project to transform from perceptual mode to scientific rational.
