摘要
运用主因子分析法对小清河济南段的污染特征进行了研究,从原始数据的相关矩阵出发,提取占总方差93%的4个主因子,对主因子及其空间变化规律做出了合理的解释。结果表明:氨氮营养盐和有机物污染因子、综合污染因子、砷污染因子和重金属污染因子是小清河济南段水质污染的4个主要因子;工业排放和生活污水是其主要污染源。
A study of the water environmental quality in Xiaoqing River was made by principal factor analysis. Based on the correlation matrix of the data, a four - factor model of the water quality in Xiaoqing River is extracted to interpret the chemical characteristics of the river. The results show that heavy metal factor, compositive factor and organic compound factor are the main factors in Xiaoqing River, which provides important information for the environmental management department to take measures to protect the river.
