摘　　要：草地退化是当今世界面临的极为严峻的生态问题之一,特别是新疆天山北坡地区的荒漠草原,由于其独特的地理环境所导致的荒漠草地退化越来越受到人们的关注。分析了新疆天山北坡荒漠草地退化的现状,在总结了国内外荒漠草地研究概况的基础上,重点综述了对新疆天山北坡地区荒漠草地退化的研究进展;在新疆天山北坡地区的荒漠草地退化研究,近年来主要集中在荒漠草地退化多样性演替、荒漠草地退化特征、荒漠草地退化遥感监测和重牧下抗牧策略等方面;通过以上综述,提出了荒漠草地退化中需要进一步深入研究的4个问题,包括荒漠草地生态系统退化机理、荒漠草地退化评价体系、荒漠草地退化监测体系和生态恢复研究,并对今后该领域的研究做出了进一步的展望和分析。Grassland degradation has been one of the extremely serious ecological problems in the world. Because of its particular character, the desert grassland degradation in northern slope of Tianshan Mountains has aroused increasing attention of scientists worldwide,and a lot of remarkable works have been done in this field. In this paper, the desert grassland degradation actuality was analyzed and the research progress of the desert grassland degradation was reviwed. The research on the desert grassland in northern slope of Tianshan Mountains,Xinjiang Province, was focused on the diversity succession,characteristics of degraded desert grass- land, the remote sensing monitoring and the response to heavy grazing pressure. The following further research should be conducted： 1） degradation mechanism of the desert grassland ecosystem; 2） evaluation system of the desert grassland degradation; 3） monitoring system of the desert grassland degradations; 4） ecological recon- struction of the desert grassland.
