Abstract
The study of groundwater hydrogeochemistry is of great significance to the development, utilization and protection of regional groundwater resources. In this paper, a complete and comprehensive analysis of three runoff zones is carried out in the Fengfeng mining area of Handan City, Hebei Province, China. The Piper trilinear diagram is used to analyze the types of karst groundwater hydrochemistry, the ionic proportionality coefficient method is used to analyze the sources of groundwater chemistry and the formation process, the chlorine-alkali index is used to react to the exchange reactions between cations, and PHREEQC software is also used to invert the groundwater simulation. The results are: the type of karst water hydrochemical in the study area is mainly HCO3·SO4–Ca·Mg; the ions are mainly influenced by rock halite, carbonate, sulphate, silicate and cation exchange; in the groundwater runoff zone, aragonite, calcite and dolomite are in saturated state, while gypsum and rock halite are in unsaturated state. The study of karst groundwater hydrochemical types, analysis of water-rock interaction and exploration of hydrogeochemical evolution mechanisms are intended to provide reference for karst water supply security and water resources utilization.
期刊介绍：
Water Resources is a journal that publishes articles on the assessment of water resources, integrated water resource use, water quality, and environmental protection. The journal covers many areas of research, including prediction of variations in continental water resources and regime; hydrophysical, hydrodynamic, hydrochemical and hydrobiological processes, environmental aspects of water quality and protection; economic, social, and legal aspects of water-resource development; and experimental methods of studies.
