| 摘 要： | 以陕西秦岭山地为研究对象,根据区域特征选取了18项评价指标进行案例研究,构建了"敏感(本底)-压力(干扰)-弹性(反馈)"的评价模型,用层次分析法确定各指标权重,综合指数法定量评价了该区域生态环境的脆弱程度,借助于ArcGIS展示了生态脆弱度的空间差异,分析了不同区域生态脆弱性的主导成因,对于该区域的生态保护、资源利用和可持续发展具有指导意义。

| Abstract: | Taking Qinling Mountains of Shaanxi as a case,according to the area characteristics,the article selected 18 indexes based on local conditions to study ecological vulnerability.After building the model of "sensitivity(situation)-pressure(disturbance)-elasticity(response)",it adopted AHP to determine the weight and used method of composite index evaluation to calculate the ecological vulnerability values.The spatial difference of ecological vulnerability was showed by ArcGIS.Lastly,it analyzed the dominant reason of different region,which will provide guiding significance for ecological conservation,resource utilization and sustainable development in the studied area. |
