| 摘 要： | 运用基于DRASTIC的模糊综合评价方法，对松嫩平原潜水的脆弱性进行了评价。分析了松嫩平原地下水环境脆弱性的主要影响因素，建立准确、适宜和完整的评价指标体系，确定最主要的7个水文地质参数。将研究区划分为75个评价单元，构建各单元归属于各个级别的最优相对隶属度矩阵，得出松嫩平原脆弱区和较脆弱区主要分布在王府-伏龙泉高台地、各条主要河流两岸及其较大支流河漫滩、低阶地以及中部的低平原地区；高平原地区和五大连池的玄武岩地区为难污染区和略难污染区的结论。

| Abstract: | Based on the fuzzy comprehensive DRASTIC evaluation method,the vulnerability of unconfined water in Songnen Plain is evaluated.The main influence factors of the groundwater environment vulnerability in Songnen Plain are analyzed to construct the proper evaluation index system exactly and to determine the seven main hydrogeological parameters.The study area is then divided into 75 cells and the subordinate degree optimal matrix of each cell for different rank is constructed.The evaluation results show that the most vulnerable zone(the zone quite easier to be polluted) is only distributed in the high land area in the south of Wangfu-Fulongquan in Jilin Province;the vulnerable zone(the zone easily be polluted) is mainly distributed along the main streams,flood plains and low terraces of their main branches and the central low plain;the least vulnerable zone is mainly distributed in the high plain area and the basaltic area in Wudalianchi. |
