应用灰关联分析法对成都龙泉山区饮用水质量分析

Study on the Application of Gray Associative Analysis on Drinking Water Quality in Longquan Mountain Area

通过对成都龙泉山区主要饮用水源宝狮湖的自来水一厂处河流和东风渠大面镇河段的自来水二厂处河流进行断面监测，运用灰关联分析方法，对饮用水环境进行综合分析。结果表明：各监测断面均属于Ⅰ类标准，自来水一厂的断面1、2与Ⅰ类标准之间的关联度为0．96，东风渠大面镇河段的断面3与Ⅰ类标准之间的关联度为0．94，符合生活用水的标准。同时针对龙泉山区的水质特点提出适当建议，使今后龙泉山区的经济与水环境达到持续协调发展。

The main dinking water source in Longquan mountain area, which is from the No. 1 waterworks in Baoshi Lake and the No. 2 waterworks locatesin Damian county reach in Dongfeng Dyke, was monitored and measured, and the drinking water environment was analyzed comprehensively with Gray Associative analysis method. The results indicated： the quality of drinking water in each monitored section accorded with the first class standard, the relevancy degrees between the first class standard and both section 1 and section 2 in No. 1 waterworks were 0. 96, and the relevancy degree between the first class standard and section 3 in the reach in Darnian county in Dongfeng Dyke was 0. 94. All the results showed that the monitored drinking water had come up with the national standard. Meanwhile, proper suggestion was provided to promote the harmony sustained development of economy and water environment in the future.
