摘　　要：利用《中国知网》(CNKI)数据库1990~2021年草地退化评价相关的688篇核心期刊文献,借助CiteSpace软件可视化功能,在系统梳理我国近三十年草地退化评价研究进展的基础上,重点分析了我国草地退化评价指标体系及其演进过程。结果表明,1990~2021年我国草地退化评价研究的核心内容是草地退化评价指标体系构建,已有评价指标中植被指标占56.5%、土壤指标占43.5%,此外草地退化评价方法、草地退化原因和退化草地修复措施也是草地退化评价研究的主要内容;我国草地退化评价研究热点最初为草地退化内涵与草地植被恢复,到2010年前后为评价方法更新与指标体系完善,近几年则为草地生态系统健康评价与草地生态系统养分平衡与循环过程研究;草地退化评价指标体系包括单独以植被或土壤为指标的单项评价,以及涵盖生态、生产、生计指标的综合评价,其中,生态指标主要包括植被、土壤指标,生产力指标包括草地生产力、草场载畜量,生计指标包括牧户感知与生计水平;草地枯落物作为草场放牧强度划分指标已被提出,由于放牧强度与草地退化有很大的关联性,因此枯落物积累量作为草地退化指示指标的意义不可忽略,并急需明确不同退化程度草地枯落物积累量的阈值。We conducted a systematic review of 688 core journal articles on grassland degradation evaluation published between 1990 and 2021 in the China National Knowledge Infrastructure(CNKI)data⁃base,using CiteSpace software for visualization.Our analysis focused on the evolution of the grassland deg⁃radation evaluation index system in China and systematically reviewed research progress over the past more than thirty years.The results showed that the primary focus of grassland degradation evaluation research during the period was the development of a comprehensive evaluation index system.Among the existing evaluation indices,vegetation indices constituted 56.5%of the total,while soil indices accounted for 43.5%.Research on grassland degradation evaluation methods,causes of grassland degradation,and res⁃toration measures of degraded grasslands have also been major areas of investigation in the field.During this period,the research focus of grassland degradation evaluation in China initially centered grassland degrada⁃tion connotation and grassland vegetation restoration.However,by 2010,the evaluation methods were updated,and the indicator system was improved.In the recent years,the research focus had shifted towards evaluating the health of the grassland ecosystem,as well as understanding the nutrient balance and cycling processes within the grassland ecosystem.The grassland degradation evaluation indicator system comprised a single evaluation with vegetation or soil as the indicator and a comprehensive evaluation cover⁃ing ecological,production,and livelihood indicators.The ecological indicators mainly included vegetation and soil,while the productivity indicators encompassed grassland productivity and grassland livestock carry⁃ing capacity.The livelihood indicators consisted of herdsman perception and livelihood level.Grassland lit⁃ter had been proposed as a measure of grazing intensity,which was closely related to grassland degrada⁃tion.Therefore,the importance of litter accumulation as an indicator for
