穆兴平原南部地区水化学特征及成因分析
Hydrochemical characteristics and cause analysis of the southern Muxing Plain
摘要
Abstract
The Muxing Plain is a typical plain-hill area in Northeast China,with unique hydrogeological condi-tions.The authors took samples of 15 groups of groundwater and 11 groups of surface water to study the chemical characteristics,formation and evolution of chemical composition of groundwater and surface water in the southern Muxing Plain,using mathematical statistics,Piper three-line diagram,ion proportion coefficient and other tech-nical methods.The results show that the groundwater and surface water are both freshwater with low total dissolved solids(TDS).The anions are dominated by HCO3-,and the cations are mainly Ca2+and Na+.The surface water is mainly composed of HCO3--Ca2+·Mg2+and HCO3--Ca2+·Na+,and the groundwater is mainly composed of HCO3--Ca2+·Na+and HCO3--Ca2+·Mg2+·Na+.The hydrochemical characteristics of surface water and groundwater are jointly controlled by water-rock interaction,cation exchange and adsorption and mineral activi-ties.The water-rock interaction is mainly silicate dissolving action,and mineral activities has an extensive-scale influence on surface water and large-degree influence on partial groundwater.The results could provide theoretical support and scientific basis for the utilization and protection of water resources in the southern Muxing Plain.关键词
