模糊聚类法在水环境质量评价中的应用

Application of Fuzzy Clustering Method in Water Environmental Quality Valuation

模糊聚类法通过数据标准化,平移及极差变换、确定最佳阙值和求解动态聚类图。该算法在长江芜湖段水环境质量评价中的应用,以选取对长江芜湖段水质影响较大的7个指标并建立其模糊相似矩阵,根据实测浓度值确定各因子的权重,结果可行。

The law of fuzzy clustering confirms the best threshold and determines the dynamic clustering figure by data＇s standardization, shift and range transform. The application of this arithmetic in the water environment＇s appraisal of the Changjiang River in the Wuhu section, select 7 indexes that make a great influence on water quality in the Wuhu section of the Changjiang River, and set up its fuzzy similar matrix, confirms each factor＇s weight according to the practical measured consistence, and the result is applicable.
