灰色聚类分析法在锦江河水质富营养化评价中的应用

Application of Gray Cluster Analysis Method to Water Eutrophication Evaluation in Jinjiang River

为更好地治理锦江河富营养化提供依据,采用灰色聚类分析法对锦江河水质富营养化程度进行评价。结果表明:1)锦江河1#位点的水质为富营养型,其余各监测位点均处于中营养型。2)灰色聚类分析法广泛应用于环境质量评价,而数据的权重值是相对的,且不同的营养指标的权重值不同,对评价指标的信息利用率较高。因此,灰色聚类分析法对环境质量的评价准确度较高。

In order to provide basis for better management of Jinjiang River eutrophication,grey cluster analysis method was used to evaluate the eutrophication of Jinjiang River water quality.The results showed that:1)The water quality of at all monitoring sites in Jinjiang Riveri was in the mesotrophic type.And the frist site was eutrophic type.2)The gray clustering analysis method was widely used in environmental quality evaluation.The weight values of each data were relative,and the weight values of different nutritional indexes were different.The information utilization rate of each index was high.Therefore,the gray cluster analysis was more accurate to the environmental quality evaluation.
