摘要
运用因子分析法对汉江各主要水质断面进行水质因子分析及综合评价,通过各主因子的方差贡献及因子得分得出各水质因子的赋权值,从而对所取断面进行水质污染程度的综合评价、分析与排序。同时运用聚类分析法对汉江17个断面的水质污染相似性进行分析,给出分类处理结果。
Factor analysis is used in the research of water evaluation of Hanjiang river .The variance contribution and factor score of principal factors are got to evaluate the pollution situation of Hanjiang river. Meanwhile the water quality survey data of 17 slices on Hanjiang are used to compare the similarity of water quality of Hanjiang river by cluster analysis.
