采用指数型白化函数建立实测值与各等级之间的对应关系,避免零权重问题,通过修正聚类权重计算体现各评价因子在同一灰类之间的变化幅度,对灰色聚类关联法将进行改进,并应用于水质评价中。对上海青浦急水港和浙江湖州新塘港2009-2013年的水质进行综合评价,结果表明,改进后的灰色聚类关联分析法评价结果更为客观准确。
採用指數型白化函數建立實測值與各等級之間的對應關繫,避免零權重問題,通過脩正聚類權重計算體現各評價因子在同一灰類之間的變化幅度,對灰色聚類關聯法將進行改進,併應用于水質評價中。對上海青浦急水港和浙江湖州新塘港2009-2013年的水質進行綜閤評價,結果錶明,改進後的灰色聚類關聯分析法評價結果更為客觀準確。

Exponential whiteness function establishes the correspondence between the measured values and each grade to avoid the problem of zero weight, and the modified clustering weight reflects the each evaluation factor ’s amplitude in the same grade of water quality. Applies the improved grey clustering relation analysis method in the water quality evaluation. After applied to water quality evaluation in Jishui Port Qingpu Shanghai and Xintang Port Huzhou Zhejiang from 2009 to 2013, the result shows that the improved grey clustering method can get evaluation result more objectively and accurately.
