摘要
运用主成分分析法(PCA)对邯郸市地下水主要污染指标年均值进行了探索性评价研究。分析结果表明,前5个主成分综合携带了全部信息的91.374%。通过对这5个新的综合指标进行分析,确定了地下水的主要污染物,同时根据其综合得分对地下水进行分级,分析了其变化趋势,为地下水资源的有效利用和保护提供了科学依据。
s: Yearly average value of major contamination index in underground water of Handan was analyzed by principal component analytical method (PCA). Results indicated 5 principal components carry 91.37% information of the whole, thus main pollutants of underground water were described and rank of water quality sorted out based on general score of these components, the trend was also analyzed, which provided scientific base for efficient use and protection of underground water resource.
