摘要
甘肃省环县多年来饮水安全问题突出,严重制约了当地社会经济的发展.综合运用统计分析、离子比例系数法、相关性分析及因子分析法对环县南部地下水样进行取样分析,旨在系统研究地下水水化学的空间分布特征及其成因.结果表明:研究区地下水主要来源于大气降水,水化学成分主要受芒硝、石膏、岩盐和碳酸盐溶解及阳离子交换作用控制.
Huan county has been with outstanding drinking water safety problems for many years, Which seriously restrict the development of local social and economy. The groundwater samples are taken and analyzed scientifically and systemically, the statistics, the ratio coefficient of main ions, the correlation matrics and factor analysis methods are used in this paper to gain a better understanding of the variation of hydrochemistry characteristics and its causes, The analysis results show that groundwater in the study area are mainly derived from the atmospheric precipitation, water chemical composition are mainly controled by the dissolution of mirabilite, gypsum, halite and carbonate and cation exchange.
