Abstract
- The karst water resources in the Fengfeng mining area are an important water supply source in the region. In recent years, due to the influence of external environment changes, the hydrochemical environment of karst groundwater has changed. In order to scientifically understand karst groundwater and rationally develop groundwater resources, it is necessary to study the hydrochemical characteristics and evolution laws of groundwater in this area. In this study, major elements in karst groundwater of different years and hydrogen and oxygen isotopes in 2022 were analyzed. The hydrochemical types of the study area were analyzed by using the Piper trilinear diagram drawn with Aquachem10.0 software. D and <superscript>18</superscript>O were used to analyze the source and elevation of groundwater recharge. Origin software was used to draw Gibbs diagrams, three-terminal diagrams, ion ratio diagrams, etc., to analyze the influencing factors of groundwater chemical components. The research results show that: (1) The groundwater in the study area is mainly HCO<subscript>3</subscript>-Ca(Mg) type water; (2) The main supply source of karst water in the study area is atmospheric precipitation, and the supply elevation ranges from 1166.7 to 1533.3 m; (3) Most of the karst groundwater in the study area is affected by the dissolution of carbonate and silicate rocks; (4) With the influence of human activities, mainly agricultural activities, with the passage of time, the impact of industrial activities on groundwater has been weakening.
