在离子强度、 pH值相同的情况下，采用一年雨量不同摩尔浓度比值的硫酸根、硝酸根模拟酸雨进行土柱淋滤的模拟试验，研究不同比值的模拟酸雨对珠三角水稻土Cd、 Cu、 Cr毒性元素释放的影响。研究表明：在离子强度不变的情况下， Cd、Cu、 Cr在不同的SO2-4、 NO3-摩尔浓度比下有不同的淋溶行为，借此可以评估硫酸型酸雨、硝酸型酸雨对农田生态系统的潜在危害，为预防与治理提供依据。

The research of Cd , Cu, Cr releasing from paddy soil in different types of acid rain was studied.The paddy soil was filled into plastic cylinder and was eluted by annual rainfall amount of simulative acid rain whose ion intensity and pH were the same , but molar concentration ratio of sulfate radical to nitrate radical was different.The study showed that in the same situation of ion intensity and pH value , different molar concentration ratio of sulfate radical to nitrate radical had different influence on the acid buffer capacity.There were different rhythms of Cd , Cu, Cr released from paddy soil , which can provide a basis for acid rain prevention and treatment.
