摘要: 根据日照市涛雒地区16组实测枯、丰两期浅层地下水数据,选取总硬度、TDS,SO2-4,Cl-,Fe,Mn,挥发性酚类,COD,NO3-,NO2-,NH4+,F,Se,Pb,Be等15项污染影响因子,使用多元统计-因子分析法对研究区内浅层地下水环境进行污染源解析。结果表明:源解析结果基本和实际污染源相一致,因子分析法对涛雒地区地下水污染进行源解析是可行的;涛雒地区主要存在4种污染特征源,它们分别是海水入侵源、冶炼源、化工源、农业生活源,对浅层地下水的污染贡献率分别为38.37%,18.49%,12.05%,11.23%。研究结果可为涛雒地区的地下水环境污染的进一步改善和治理提供参考。

Abstract: According to 16 groups of shallow groundwater data in dry and wet season in Taoluo area, Rizhao City, we selected 15 pollution influential factors such as total hardness, TDS, SO2-4, Cl-, Fe, Mn, volatile phenolics, COD, NO-3, NO-2, NH+4, F, Se, Pb, Be to analyze the pollution source of shallow groundwater by using Multivariate statistics-factor analysis. The results show that:the source apportionment results is consistent with the actual pollution sources, proving that the factor analysis results are reliable; there are mainly four pollution characteristic sources including seawater intrusion sources,smelting sources,chemical industry sources,agricultural and domestic sources, the contribution rates to shallow groundwater pollution are 38.37%,18.49%,12.05%,11.23%, respectively. These results can provide indications for further improvement and management of groundwater environmental pollution in Taoluo area.
