摘　　要：在阐明六盘水市生态系统脆弱性作用机制的基础上,构建评价指标体系,借助综合指数法对六盘水市2003-2014年的生态系统脆弱性进行评价分析,结果显示:特殊的自然环境是六盘水市生态系统脆弱性产生的根本原因;资源型产业的发展、庞大的人口压力和贫困是六盘水市生态系统脆弱性加剧的外在驱动因子;生态系统敏感性和应对能力整体上都在增强,但前者增速明显慢于后者,因此生态系统脆弱性总体下降;脆弱性等级由高度(2003-2010)演变为中度(2011-2014),反映六盘水市生态系统正在向良性方向发展,但目前脆弱性仍较高.根据上述结论,进一步提出了降低六盘水市生态系统脆弱性、促进其可持续发展的措施.Based on clarifying the functionary mechanism of ecosystem vulnerability in Liupanshui, the author constructs evaluation index system and evaluates the ecosystem vulnerability in Liupanshui from 2003 to 2014 by comprehensive index method. The results indicate that the fundamental cause of ecosystem vulnerability in Liupanshui lies in its special natural environment; the external driving factors, like the development of resource-based industries, severe population pressure and poverty, lead to intensifying the ecosystem vulnerability; the sensitivity and coping ability of ecosystem are generally increased, but the growth rate of the former is slower than that of the latter, therefore, the ecosystem vulnerability is generally declined; the vulnerability level evolves from high vulnerability（2003- 2010）to moderate vulnerability（2011-2014）, which reflects the ecosystem is developing in a benign direction in Liupanshui, but the vulnerability is still high. According to the conclusion, the author puts forward some measures to reduce the ecosystem vulnerability in Liupanshui and to promote its sustainable development.
