| 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。

| Abstract: | The karst regions in Chongqing are typical eco-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 eco-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. |
