摘要
本文以山西省地级市为基本研究单元,依据相关理论,运用层次分析法,选取了12项评价指标,对山西省生态环境脆弱性进行了评价,确定各了个地级市的生态环境脆弱性度量指数EVI值,并分析了山西省生态环境脆弱性的分布特征。研究结果表明:山西省的生态环境总体呈中度脆弱性,太原市的生态环境脆弱性最强,晋城市脆弱性最弱。
Taking the prefecture-level city in Shanxi province as the basic research unit,according to the related theory and selecting 12 evaluation indexes,the eco-environment vulnerability in Shanxi province was evaluated by using AHP,and the ecoenvironmental vulnerability index(EVI) value of each prefecture-level city was determined.The distribution characteristics of ecoenvironmental vulnerability in Shanxi province were analyzed.The results showed that the overall eco-environmental vulnerability of Shanxi province was at a middling level,while Taiyuan city showed the highest vulnerability and Jmcheng was the lowest one.
