基于PSR模型的矿区生态安全评价研究——以河南义马矿区为例

Ecological Security Evaluation in Henan Yima Mining Area Based on the PSR Model

运用压力—状态—响应模型构建了矿区生态安全评价指标体系,并采用层次分析法确定各个指标的权重,同时以河南义马矿区为典型代表,运用综合指数法来评价义马矿区2007年-2013年的生态安全状况。评价结果表明:虽然义马矿区的生态安全指数呈逐年增长的趋势但仍处于重度不安全的风险状态,需要引起该地区的高度重视。

The mining area ecological security evaluation index system is constructed based on the pressure-state-response model,and AHP is used to determine the weight of each index. Taking Henan Yima mining area as the typical representative,the method of comprehensive index is adopted to evaluate the ecological security of Yima mining area from 2007 to 2013. The evaluation results showed that： although the ecological security index of Yima mining area is increasing year by year, it is still at the state of severe insecurity, which needs to be paid close attention.
