通过建立生态环境脆弱性评价指标体系,选择压力-状态-响应模型,对宁夏南部山区生态环境进行了定量评价,得到了各个评价单元的生态脆弱性相对强弱得分,同时运用Arcgis软件对区域的生态脆弱性进行分级.结论表明,评价单元脆弱性主要集中在强脆弱性和中脆弱性之间,其中原州区和隆德县为强脆弱区,泾源县、海原县、西吉县、彭阳县属于中脆弱区.

The eco-environmental vulnerability of Ningxia south mountain areas was evaluated through establishment of eco-environmental vulnerability evaluation index system and selection of pressure-state-response model.Using this method,assessment unit ecological vulnerability relative score was gained for each,and grades of ecological vulnerability were gained with Arcgis software.Conclusions show that vulnerability grades of unit are mainly medium or strong values,Yuanzhou District and Longde County are medium-vulnerable regions,Jingyuan,Haiyuan,Xiji and Pengyang County belong to strong-vulnerable regions.
