| 摘 要： | 地下水脆弱性评价与编图是保护地下水环境工作的基础，DRASTIC模型是目前国际上最普遍应用的地下水脆弱性评价方法。在利用GIS进行地下水脆弱性评价的基础上，引进基于熵权的模糊优选评价方法，构建了基于熵权与GIS耦合的DRASTIC地下水脆弱性模糊优选评价模型。将该模型应用于黄水河流域，计算出了各评价参数的熵权和各叠加分区基于熵权的隶属度，据此将地下水脆弱性划分为高、中、低3个等级。结果表明，评价过程中避免了人为因素的干扰，更能真实地反映客观情况，为地下水脆弱性的评价提供新的思路和方法。

| Abstract: | Groundwater vulnerability assessment and mapping are the basic work for groundwater environment protection.DRASTIC index system is the most popular in the world.The entropy weight fuzzy optimization method was introduced to groundwater vulnerability assessment coupled with GIS in this paper.It avoids the influence of human factor when the parameters weight is evaluated.Taken Huangshuihe river catchment as an example,the entropy weight of DRASTIC parameters and the optimal degree of overlay area were calculated.Thus,the groundwater vulnerability of Huangshuihe river catchment was divided 3 grades:high,medium and low.A good effect of the application is obtained. |
