///Based on element analysis on the overlying bedrock and soil and system monitoring on cations concentration in spring water, soil infiltrating water and cave drip water in the Furong Cave, Chongqing, it is found that the concentration of Ca2+, Mg2+, Sr2+ and SO42- have obvious differentiation during the processes of migration among bedrock, soil and water in epikarst zone. The average mass ratio of Ca2+, Mg2+ and Sr2+ is 239 949 ppm, 129 607 ppm and 123 ppm, respectively in bedrocks; 37 458 ppm, 28 360 ppm and 49 ppm in soil; 25.55 mg/L, 11.04 mg/L and 0.026 mg/L in soil infiltrating water; 64.37 mg/L, 37.87 mg/L and 0.044 mg/L in cave drip water. Ca, Mg and Sr appear significant eluviation and illuviation on the soil profiles and their content directly control the concentration of corresponding element in soil infiltrating water.
