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.
