摘要
以延河为例,运用因子分析方法和聚类分析方法就各监测断面水质污染程度和污染相似性进行定量化的综合评价。提出水质污染的逐步回归分析方法,并以年水质综合污染指数为例,对其进行逐步回归分析。为合理评价延河水环境状况提供一定的科学依据。
Using the methods of factor analysis and cluster analysis, the paper has made the quantitative analysis and comprehensive assessment for the polluting status in degrees and in similarities of monitoring sections in Yanhe River. A method of stepwise regression analysis on water polluting is discussed with examples of the comprehensive water polluting index. It can be provided some scientific bases to assess the water environment situation of Yanhe River.
