中国草地灌丛化研究进展
Research Progress on Shrub Encroachment in China
摘要
Abstract
Shrub encroachment,which significantly alters structure and function of grassland ecosys-tems,is a critical ecological issue in China.To obtain a comprehensive and quantitative understanding of the research trends on shrub encroachment research in China,this study conducted a bibliometric analysis using CiteSpace and a meta-analysis based on published literatures on shrub encroachment in China since 1970s.Research on shrub encroachment in China had developed rapidly in recent years,with a primary focus on the drivers of shrub encroachment and its impacts on soil,vegetation,and biodiversity.Studies on shrub encroachment in China had been predominantly conducted in drylands and alpine regions.Major driv-ers of shrub encroachment included grazing management,climate change,habitat characteristics,and fire.Shrub encroachment was found to have a negative impact on soil quality but a positive effect on community composition,as well as the structure of vegetation and microbial communities in China.The primary man-agement techniques for shrub encroachment included grazing exclusion,grazing management,physical removal,and prescribed burning.This study provides scientific insight into the drivers,impact,and future management strategies for shrub encroachment in Chinese grassland.In the future,it is necessary to strengthen large-scale dynamic assessments of shrub encroachment across diverse grassland types,and inte-grate remote sensing technology to enhance the scientificity and effectiveness of monitoring and manage-ment of encroached landscape in China.关键词
