Chemical Characteristics and Evolution Mechanism of Groundwater in Xingfuhu Spring Area
The long-term mining behavior has seriously damaged the process of groundwater recharge,runoff and discharge in the Xingfuhu spring area.Based on mathematical statistics,Paper three line diagram,Gibbs diagram and other research methods,this paper analyzed the chemical characteristics and control factors of groundwater in the Xingfuhu spring area after the change of groundwater flow field.The results show that the main type of groundwater in the study area is HCO3-Ca·Mg,the source of groundwater solute is mainly carbonate and silicate weathering,the dissolution of silicate can not be ignored,there is reverse cation alternative adsorption in groundwater,which makes the con-centration of Na+and K+decrease while the concentration of Ca2+and Mg2+increase.Human domestic sewage and industrial activities are the main controlling factors affecting the composition of groundwater in the study area.
