Optimization of Groundwater Exploration Targets in Ganzhou Red Bed Basin and Surrounding Areas Based on AHP-GIS Coupling Model
摘要
Abstract
To address the challenges in selecting optimal groundwater exploration targets in the red-bed basins of southern China,this study focuses on the Ganzhou Basin and its surrounding areas.By constructing an AHP-GIS coupled multi-factor comprehensive evaluation model,we systematically integrated 10 indicators from four major categories-geological structure,topography,meteorology-hydrology,and land cover-to conduct quantita-tive evaluation of groundwater potential and optimize exploration targets.The results indicate that the groundwa-ter potential index in the study area exhibits a distribution pattern of"low in the basin center,moderate at the edges,and high in mountainous regions,"with high-potential zones concentrated in the mountainous areas on the eastern and western sides.The aquifer formation(weight 0.29)and small watershed catchment area(weight 0.21)are identified as the core factors influencing groundwater recharge and enrichment,while struc-tural density and vegetation coverage jointly regulate groundwater movement and recharge capacity.The delin-eated high-potential target zones(B1-B5)are all located in composite areas characterized by high aquifer suit-ability scores,large catchment areas,well-developed structures,and high vegetation coverage.Drilling valida-tion revealed that the water yield per well in these target zones ranges from 611.71-1,381.33 m3/d,with model cal-culations showing high consistency with pumping test data.The findings enable spatial identification and hierarchical evaluation of groundwater exploration targets in the Ganzhou red-bed basin and its surroundings,providing reliable technical support for precise groundwater exploration and sustainable development in southern red-bed regions.关键词
