摘　　要：生态环境的恶化导致生态系统的格局、过程和服务功能发生改变,进而威胁生态系统和社会经济的持续发展。因此,生态系统脆弱性研究是当前生态系统研究的重要内容,也是适应和减缓环境恶化的关键。本文对国内外相关研究中出现的生态系统脆弱性概念进行了归纳、总结,阐述了笔者的理解,并提出应规范生态系统脆弱性的命名,以加强不同领域间的交流;综述了国内外生态系统脆弱性研究的侧重点以及可供借鉴的评价方法,研究者可以根据研究的目的和研究对象的特点选择适宜的评价方法,同时应积极探讨适合研究区域的更准确更方便的评价方法;最后,探讨了该领域研究面临的挑战,而这也是今后脆弱性研究需要解决的问题。The pattern, processes and services of ecosystem has been changed because of eco-environment deterioration, and then the sustainable development of ecosystem and social economy are threatened. Ecosystem vulnerability research is important for studies of ecosystem, and is also the key to adapt to and slow environment deterioration down. This paper analyzed and summed the different definitions of ecosystem vulnerability from literatures both abroad and domestic. Based on this, we discussed our understanding of the term, and suggested a nomenclature for ecosystem vulnerability to enhance communication between different areas; then, the paper reviewed the evaluation methods of ecosystem vulnerability. Researchers can select proper methods according to their aim and the character of the object of study, meanwhile, new assessing methods should be developed for convince and precision. Finally, we discussed the development tendency and issues which should receive more attention in this area.
