摘要
为了寻求最佳的地下水水质评价方法,简述了综合评价法、模糊综合评价法和改进密切值法的基本原理,并应用这三种方法对银川市宁夏化工厂Ⅰ水源地地下水水质进行评价,通过对评价结果进行对比分析,结果表明:综合评价法夸大了最大值的作用,使评价结果略显严格;模糊综合评价法的水质评价结果比综合评价法更合理,但是相对于其他两种方法计算略显复杂;改进密切值法简便易行,评价结果合理,并可提供许多潜在的信息,在研究区得到了很好的应用,是开展水环境质量综合评价的一种十分有效的方法,值得推广。
In order to seek the best evaluating method for groundwater quality,the paper outlined the basic principles of comprehensive evaluation method,fuzzy comprehensive evaluation method and improved osculating value method,carried out the evaluation of the groundwater quality for Ⅰ Water Sources of Ningxia Chemical Plant in Yinchuan.Used these three methods.Through the comparative analysis,the results showed that the comprehensive evaluation method has aggrandized the role of the maximalvalue,so that the evaluation results were somewhat strict;the assessment results by the fuzzy comprehensive evaluation method were more reasonable than the comprehensive evaluation method,but the calculation was too complex than that of the other two methods;the improved osculating value method was simple and easy in use,and the evaluation results were reasonable and can be provide a lot of potential information,it was a very effective method and worth popularizing for comprehensive assessment of water environment quality evaluation.
