AHP法在江西脆弱生态环境评价指标体系中的应用

根据区域脆弱生态环境评价指标体系建立的原则，结合本区脆弱性的特点，建立了江西省脆弱生态环境评价指标体系；采用AHP法计算各指标的权重，得到了4个层次的层次单排序。在此基础上，确定了各层次各因子相对的权重，用于评价江西省脆弱生态环境的脆弱程度。结果表明，江西省脆弱生态环境评价指标体系中，目标要素B以人为干扰脆弱（B2）为主，占73％；指标层（D）中20个指标相对应总目标A的权重值排序结果显示，森林覆盖率所占的权重最大，达0．2044，水土流失强度的权重次之，为0．1825，二者占20个指标的比例达39％之多，平均各占19．5％；其他18项指标之和只占61％，平均各占约39％，且单项权重值均小于0．1，足以反映影响江西省脆弱生态环境程度的主导因子是人为干扰脆弱为主，即森林覆盖率和水土流失强度。

The Application of Analylic Hierarchy Process(AHP) Method on Fragile Eco-Environment Evaluation in Jiangxi Province

According to the regional vulnerability of the eco-environment evaluation index system set up the principles,combined with the vulnerability of the district characteristics,Jiangxi Province,set up a fragile eco-environment evaluation index system;and using AHP method to calculate the weight of each indicator has been the level of four-level single-Sort.On this basis,determine the various levels of the factor relative weights for the evaluation of Jiangxi fragile eco-environment vulnerability.The results sho...
