摘　　要：随着气候变化和人类活动干扰的加剧,草地灌丛化现象愈加普遍,已发展成全球性问题,是如今草地环境学、草地生态学、旅游学、土壤学、畜牧学等学科研究的热点和前沿。本文分别从气候变化和人类活动两方面总结了草地灌丛化的潜在成因,在此基础上梳理了草地灌丛化对生物多样性的影响,进一步总结了草地灌丛化影响生物多样性的潜在途径,并对未来的研究方向作了展望。研究成果对我国履行“昆明—蒙特利尔生物多样性框架”和实现到2030年全球土地退化零增长目标等具有重要意义。As climate change and intensified human disturbances continuing,the phenomenon of shrub encroachment in grasslands is increasingly prevalent and has evolved into a global issue.It has become a focal point and frontier in disciplines such as grassland environmental science,grassland ecology,tourism,soil science,and animal husbandry.This paper provides a comprehensive summary of potential factors from both climate change and human activities.Building upon this,the paper outlines the impacts of shrub encroachment in grasslands on biodiversity,further examines potential pathways influencing biodiversity,and makes a further prospect for the future research direction.It highlights the importance of addressing shrub encroachment for China′s implementation of the Kunming-Montreal Biodiversity Framework and achieving global goals such as zero net land degradation by 2030.
