摘要Carbonate weathering by CO2 is considered to play an important role in the global carbon cycle. In acid rain-affected areas, the carbon cycle can be impacted by acid rain weathering. When previous studies have considered all possible weathering processes including H2SO4 in rainfall, sulfide oxidation and agricultural activities, this study proposed a geochemical method to specifically calculate the extent of carbonate weathering by acid rain using hydrogeochemical data from karstic spring and rainfall. This method has considered the H concentration and nitrification of NH4 in rain during recharge, and provided the upper limit of the weathering amount. Seasonal sampling for spring (wet and dry season) was conducted from a typical carbonate area in Jiaoshi, Chongqing, SW China, with annual rain pH values ranging from 3.94 to 4.70. The major hydrogeochemistry types of spring are HCO3-Ca and HCO3-Ca center dot Mg. The average proportion of carbonate weathering by acid rain is estimated to be 36 +/- 15%. The quantitative geochemical method provided in this study is important for understanding the hydrogeochemical processes in acid rain areas and for calculating CO2 sources & sinks of carbonate weathering.
