摘　　要：张士灌区细河流域地下水中有机和无机污染均较为严重,其污染原因和污染特征受多种污染源的控制。简要地概述了污染质的空间分布特征,并应用富集因子和因子分析法研究分析了污染质的来源,判别污染源的贡献度。研究结果表明,地下水污染源有面源污染、线源污染、点源污染;其中属于面源污染的污染物主要有氨氮、硝氮、硫酸根、菲、六氯环已烷、铁和锰;属于线源污染的污染物主要有氨氮、汞、镉、COD、菲、六氯环已烷等;属于点源污染的污染物有硫酸根、乐果、氰化物。由此看出,张士灌区细河流域不仅存在大范围的农药、肥料对地下水造成污染,也存在化工企业的外排废水对地下水造成的污染。Groundwater in Zhangshi irrigated area is seriously polluted by both organic and inorganic pollutants, the spatial distribution of pollutant and characteristics are as a result of various sources of pollutant. The authors simply summarize the spatial distribution of pollutant enrichment factor and factor analysis methods are applied to study the sources of pollutant, and the contributing degree of each source. The result shows that the sources of pollutant mainly include non-point-source, line-source and point-source, with NH^＋4 , NO^-3, SO^2-4 , phenanthrene, BHC, Fe and Mn mainly from non-point-source, NH^＋4, Hg, Cd, COD, phenanthrene, BHC mainly from line-source, and SO^2-4 , dimethoate and CN-from point-source. Taking acconnt of above discussing, groundwater is not only pollutant by pesticide and fertilizer, but also by waste water from chemical plunt.
