熵权物元分析模型在海水水质评价中的应用

Application of Matter Element Model Based on Entropy Weight to Evaluation of Seawater Quality

根据熵权法确定评价指标权重,利用物元分析方法对2004年长江口及邻近水域渔业环境水质状况进行综合评价,评价结果与灰色聚类法进行对比。结果表明,利用熵权物元分析模型进行海水水质评价是合理可行的,且评价结果分辨率更高。同时本研究为海水水质评价提供了新的思路和方法。

Entropy weight is used to calculate the weight of evaluating indicators, then a matter element model is also adopted to evaluate the environmental quality of the seawater quality in the Changjiang River estuary and fishery waters nearby for 2004. The results are compared with that of the grey clustering method, the results indicate that the matter element model is feasible for evaluating the seawater quality and more resolving power. At the same time, the study expands the new ideas and methods of the seawater quality.
