摘要
为了研究涉县东风湖泉域地下水化学特征,通过聚类分析、社交网络分析与因子分析对泉域内14个岩溶水样9个指标系统分析,结果显示:研究区水化学类型主要为HCO3-Ca·Mg型或HCO3-Ca型,R型聚类分析与社交网络分析根据9个指标相关性划分两类,Ⅰ类主要体现盐岩溶滤与阳离子交换作用,第Ⅱ类主要是地下水中酸碱演化作用。研究区水化学特征主要受F1、F2两个主因子影响,主因子F1以K^+、Na^+、Mg^2+、CL^-、HCO3^-、TDS为主,表明水化学特征主要受盐岩溶滤、阳离子交换以及酸碱演化作用所控制;主因子F2以Ca^2+、SO4^2-、PH为主,揭示影响水化学特征主要为硫酸盐矿物溶解作用。
In order to investigate Characteristics of groundwater chemistry around Dongfeng lake in She county of Hebei province,through cluster analysis,social network analysis and factor analysis,a systemic analysis of 14 water samples and 9 indicators in the spring area.According to the survey:the groundwater chemical type in the study area is dominated by HCO 3-Ca·Mg、HCO 3-Ca,R-type cluster analysis and social network analysis are divided into two categories based on the correlation of 9 indicators.Category Ⅰ mainly reflects the effects of salt karst filtration and cation exchange,and Category Ⅱ is mainly the evolution of acid-base in groundwater.The water chemistry characteristics of the investigating area are mainly affected by two main factors,F1 and F2.The factor F1 is mainly K^+,Na+,Mg^2+,CL^-,HCO^3-,TDS,and it shows that the water chemistry characteristics are mainly controlled by salt karst filtration,cation exchange and acid-base evolution;the factor F2 is mainly Ca^2,SO42-,PH,revealing that the main influence on water chemistry characteristics is sulfate minerals Dissolution.
