摘要
利用多元统计的因子分析方法对采自于山东枣庄小沙河7个断面的17份水样数据进行分析,将4个评价指标转化为有机质污染因子和有毒有害污染因子,通过因子模型和因子得分表达式刻画小沙河的水质污染情况,得出第一、二断面水质污染最为严重。
Using multivariate statistical method of factor,the data of 17 water samples from 7 sections were analyzed.Conversing the four evaluations into organic pollutants and toxic pollutants,the water quality of pollution in Xiaosha River was characterized by expression of factor models and factor scores.The results showed that water pollution of first and second sections were the most serious.
