中文摘要：
重庆岩溶区属典型的生态环境脆弱区，宜耕地资源不足．土地退化严重，承受自然灾害能力低，使岩溶地区的社会经济发展和生态环境的协调性差，可持续发展能力弱。本文以重庆市岩溶地区为例。选择12项生态环境脆弱性影响因子为评价指标，利用层次分析法赋予指标权重，然后建立模糊数学模型对岩溶地区生态环境脆弱性进行评价研究。结果表明：重庆市25个岩溶区县中潜在脆弱区县7个。轻度脆弱区县2个，中度脆弱区县5个，重度脆弱区县5个，极度脆弱区县6个。
英文摘要：
The karst regions in Chongqing are typical coo-environment vulnerable areas, where plowland is insufficient and degeneration of soil is serious, the ability to endure the natural calamities is vulnerable. Consequently, coordination between development of social economy and eco-environment is badly, and ability of sustainable development is infirm. This paper sets the karst areas of Chongqing as a case , picks up 12 influencing factors of eco-environment vulnerability to be assessment indicators, and uses Analytic Hierarchy Process（AHP） to give weight for different assessment indicators, then sets up a model of fuzzy mathematics to analyze and evaluate the coo-environment vulnerability of karst areas. Results indicate： there are 7 potentially vulnerable counties, 2 gently vulnerable counties, 5 moderately vulnerable counties, 5 seriously vulnerable counties and 6 extremely vulnerable counties among the 25 karst counties in Chongqing.
