在西辽河平原地下水资源评价的基础上,选取影响西辽河平原固有脆弱性的最主要的7个影响因子,利用GIS平台的空间分析功能.将研究区划分为14365个评价单元,运用基于DRASTIC的模糊综合评价方法对该区的地下水固有脆弱性进行了综合评价.并绘制了脆弱性分布图.评价结果表明西辽河平原(内蒙古部分)地下水脆弱性存在3个分区:大部分地区为地下水稍易污染区:南部的黄土地区为地下水稍难污染区;而西辽河和乌尔吉木伦河的中上游为地下水相对略易污染区.评价结果对该区地下水资源保护、防止地下水污染具有指导作用.

Based on the results of groundwater resources evaluation in West Liaohe plain.the iTlain seven effect factors that infuence intrinsic vulnerability are selected.With the spatial analysis fimction of GIS the stuay area is divided into 14365 evaluation units.Thereafter,the groundwater vulnerability is evaluated with the comprehensive fuzzy evaluation method on the basis of DRASTIC,and the groundwater vulnerability map is developed afterwards.The results show that groundwater vulnerability in West Liaohe plain (In-net Mongolia part)Can be cataloged into three zones-most area where it is quite easier to be poUuted,the southern loess area where it is quite more difficult to be polluted and the zone easily to be poUuted in West Liaohe and Wuerjimulun River.The evaluation result is available for the effective protection of groundwater resource and the prevention of groundwater poHution.
