基于模糊综合评判法评价地下水环境质量的探讨——以新疆某市为例

模糊综合评判法是以模糊数学为基础,应用模糊关系合成的原理,将一些边界不清,不易定量的因素定量化,进行综合评价的一种方法。从其原理分析,在地下水环境质量评价方面可能取得更准确的结果。首先介绍了模糊综合评判法的计算步骤,然后以新疆某市2008年第4季度2个水质监测采样点的监测资料为依据,选择5种污染物为评价因子,运用模糊综合评判法进行运算,得出综合评价结果。评价结果表明,运用模糊综合评判法评价地下水质量是合理的,其评价结果能全面反映水质的综合状况。

Groundwater Environmental Quality Assessment Based on Fuzzy Comprehensive Evaluation Method——Take One City of Xinjiang as an Example

Based on fuzzy mathematics and synthetic principles of fuzzy relationship, fuzzy comprehensive evaluation method can quantify some boundary faintness factors that is difficult to estimate. Therefore, the method can achieve more rational results if it is used to assess the quality of groundwater. The calculation steps of fuzzy comprehensive e- valuation are introduced fist. Than, based on the data of the fourth season in 2008 that come from two monitor points of water quality in one city of Xinjiang, five pollutants are selected as evaluation factors, and the comprehensive water quality status of two monitor points are calculated by using the fuzzy comprehensive judgment. The results show that it is reasonable to use fuzzy comprehensive evaluation method to assess the quality of groundwater situation, and the out- comes can reflect the comprehensive situation of monitor points completely.
