摘要
通过对安徽池州南郊地下水调查及样品测试分析,发现近22年来该地区地下水水化学类型已由简单变为复杂。与1990年比,2012年HCO3-Ca和HCO3-Ca+Mg型地下水分布面积显著缩小,HCO3-Na+Ca型地下水完全消失,HCO3+SO4-Ca型地下水出现并大面积分布。认为造成这种现象的主要原因是该地区近年来酸雨频发及工矿企业污染物排放。
By investigating the groundwater and analyzing the samples in the south suburbs of Chizhou city, An- hui Province, it is discovered that the hydroehemical types of groundwater in this region have become from simple to complicated in recent 22 years. In comparison with 1999, in 2012, the distribution area of the HCO3--Ca type groundwater and HCO3-Ca＋Mg type groundwater decreased significantly, the HCO3- Na＋Ca type groundwater disappeared, and the HCO3＋SO4Ca type groundwater appeared with large distribution area. It is believed that the main reasons for this phenomenon are the frequent acid rains and pollutions of industrial and mining enterprises.
