基于灰色局势决策分析的地下水环境质量评价

概要叙述了灰色局势决策分析的原理及其在环境质量评价中的应用方法，就阜新新邱露天煤矿排土场淋溶水对附近于家沟地区地下水环境质量的影响进行了评价研究。对研究区内的17眼水井分别采样，进行水质分析，识别出总硬度、硫酸盐、硝酸盐、氯化物、溶解性总固体、高锰酸盐指数等主要污染因子，采用灰色局势决策方法对影响区内的每个监测点位的水质进行了评价，确定出地下水环境质量的等级，并将该评价结果与模糊综合评价法、灰色关联分析法和灰色聚类分析法相比较，为污染区地下水水质的区划提供了可靠依据。

Grey situation decision analysis of environmental quality of underground water contaminated by leachate of the dumping area

The principle of grey situation decision and its applied method in environmental quality assessment were expounded briefly, and the question of the influence on underground water quality in the area of Yujiagou of the leachate of the dumping area of open pitcoal mine of Xinqiu in Fuxin was studied in this paper. Firstly, authors took samples from 17 water wells in the study area, analyzed samples for water quality, recognized the main pollution factors, such as total hardness, sulphate, nitrate nitrogen, chlorinate compound, dissolved solid, permanganate index etc., then, assessed the water quality of each water wells making use of grey situation decision method, gave out the classifications of the underground water quality of the study area. Compared with grey -clustering analysis method, grey associated analysis method and fuzzy comprehensive appraisal method, it is demonstrated that the results of the water quality appraisals gained by four methods are identical basically.
