摘要
首先介绍模糊数学在国内水质评价中的应用及其优势,分析其在地下水水质评价中的原理和方法。然后以德阳市20组水样分析资料为基础,应用模糊数学原理对其地下水质进行模糊综合评价。结果表明,区内地下水水质无I级,Ⅱ级占15%,Ⅲ级占45%,Ⅳ级占10%,Ⅴ级占30%。工业排放、生活垃圾和原生铁锰超标是部分地区水质污染或超标的主要原因。
An introduction is made to the domestic practices, advantages, principles and methods in applying fuzzy mathemat ics to water quality assessment. Then the groundwater in Deyang is evaluated through a fuzzy math study of the twenty samples collected there. As a result. 15%, 45%, 10% and 30% of the groundwater in tile subject area is identified as Grade B, C, I） and E respectively without Grade A. The major causes of water pollution in this area are found to be industrial discharge, do mestic waste, and excessive original iron and manganese.
