| 摘 要： | 松嫩平原是东北地区重要的能源交通工业基地和农牧业基地。近几十年来,在发展经济的同时,自然生态环境也在遭受着破坏,产生了许多环境地质问题。本文运用基于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。在评价的过程中分析了影响松嫩平原固有脆弱性的最主要的7个水文地质参数,将研究区划分为75个评价单元,应用公式构建各单元归属于各个级别的最优相对隶属度矩阵,得出脆弱性评价结果,绘制出脆弱性分布图。结果表明脆弱区(易污染区)只分布在吉林省王府~伏龙泉南部高平原区很少一部分;较脆弱区(略易污染区)主要分布在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区。评价结果有利于合理利用土地,有效保护地下水资源和防止地下水污染。

| Abstract: | Songnen Plain is the important base of energy,traffic,industry,agriculture and livestock in northeast China.With the development of economy recently,the natural ecological environment has been destructed at the same time,which results in many environmental and geological problems.In this thesis,the vulnerability of unconfined water in Songnen Plain is evaluated with the comprehensive fuzzy evaluation method based on DRASTIC.In the process of evaluation,the seven main hydrological parameters that influence the vulnerability are analyzed,and the study area is divided into 75 cells.Then based on the formula the optimal matrix is constructed to get the evaluation results and the vulnerability map.The results show the most vulnerable zone(the zone quite easier to be polluted) is only a small area of the high plain in the south of Wangfu~Fulongquan in Jilin Province;the vulnerable zone(the zone easily be polluted) is mainly along the main streams,flood plains and low terraces of their main braches and low plain in the center of thes area.The evaluation result is available for the reasonable use of land,the effective protection of groundwater resource and the prevention of groundwater pollution. |
