摘要
针对长江流域日益严重的水污染现状,根据流域各站点的检测值,利用灰色关联分析法建立模型,并对长江水质进行了定量综合评价.通过计算抽样水质与《地表水环境质量标准》(GB3838-2002)中各限值的关联度,得出各时间点(某断面不同时段)的水质综合评价指标,从而判断水质类别,同时还得出了各断面水质的演变趋势.
Aiming at the water quality pollution of the Yangtze River, the Yangtze Drainage Area water quality is evaluated comprehensively based on the monitoring data using the grey correlative degree analysis method. By computing the rank between the sample water quality and the threshold value in Surface Water Quality norm（GB3838-2002）, the general assessment indicators on different times （different periods of one section） are got and water quality are judged. At the same time, the water quality evolutionary tendency of different sections is forecasted.
