Understanding the hydrogeological structure and hydrogeochemical processes of karst aquifers is critical for groundwater management. This study innovatively integrates drilling, tracer tests, high-resolution monitoring, and multi-isotope techniques (3H, 14C, δD, δ18O) to systematically characterize the spatial heterogeneity of a multiple karst aquifer system. Hydrochemical data was analyzed with the electrical conductivity decomposition method. Multivariate statistical analysis and the ions ratio are used to identify the sources and components of the spring water during storm events. The results indicate that: (1)The upper and lower aquifer systems are composed of limestone and dolomite, respectively, while the intermediate aquifer system is constituted by both limestone and dolomite. The upper and intermediate aquifer systems exhibit conduit flow regimes, whereas the lower aquifer is characterized by fracture flow. The lower aquifers (∼13,862-year residence time) show unique SO
