| 摘 要： | 在灰色聚类方法的基础上,引入熵权概念,并通过熵权修正指标的权重系数,充分利用了样本信息.利用基于熵权的灰色聚类法对长江库区13个监测断面水质质量进行综合评价,获得较好效果,并与模糊综合评价方法比较,其计算简便,结果更客观、合理.

| Abstract: | This paper bases on grey clustering method,introduces the concept of information entroy,and makes full use of the sample data by modifying the weight of grey clustering with the entroy weight.Assess the water quality of the 13 monitoring sections of the Three Gorges reservoir area by method of the information entroy-based grey clustering,and we get a good result.Compared with fuzzy synthetic assessment,it is more convenient,and the assessment results are more reasonable. |
