A study was conducted on variations in chemical composition of surface and spring water in a typical karst peak cluster-depression catchment, Northwest Guangxi, during two rainfall events on Aug 23rd and Aug 24th, 2007. Both spring and surface waters displayed a quick response to the rainfall in terms of water chemistry. The solutes transportation rates of spring and stream flows increased during the rainfall period, but didn’t show a positive relationship with rainfall intensity during continuous rainfall, revealing that besides the rain dilution effect and soil CO₂ effect, the pre-event water stored in the soil vadose zone, as well as the amounts of exchangeable ions may affect the transportation of ions of both spring and stream flows in the karst peak cluster-depression catchment during rainfall.
