改进权重集对分析法在准东水质评价中的应用

摘要

According to the water sources of Zhundong groundwater quality monitoring data in September 2011,we used greater impact on groundw-ater quality factors for the evaluation of the project,such as total hardness,total dissolved solids,sulfates and chlorides based on the improved weight set with multiple superscalar entropy analysis of Zhundong’s five groups of water sampling data water quality evaluation. The results show that improved weight set for analysis in the calculation considering the importance of the evaluation project,make the results closer to the objective reality;the most of the water quality of Zhundong is Class I and II,the overall situation is good and it is not contaminated basically.%根据准东水源地2011年9月地下水水质监测资料，以对地下水水质影响较大的总硬度、溶解性总固体、硫酸盐和氯化物为评价项目，采用基于熵权与超标倍数赋权的改进权重集对分析法对准东水源地进行了水质评价。结果表明：改进权重集对分析法在计算时考虑了各评价项目的重要性，使计算结果更接近客观实际；准东水源地大部分水质为Ⅰ级和Ⅱ级，水质总体情况较好，基本未受到污染。
