摘要
利用信息熵确定了指标的区分权重,建立了基于指标分类权重的未确知测度综合评价模型,并应用未确知测度综合评价模型评价了长江7个观测站点2003年6月至2005年9月的水质状况.从而为长江水质评价提供了一条新的途径.
The weight of index classification is determined using the information entropy,and then the unascertained comprehensive evaluation model based on the index categorization is established.The water quality of the seven observation stations in the Yangtze River is evaluated from June 2003 to September 2005 based on the unascertained comprehensive evaluation model.This will provide a new way for water quality assessment of the Yangtze River.
