摘　　要：通过主要燃料煤和燃油以及雨水中硫、氮稳定同位素成分谱的分析,应用受体模式解析大气和降水中硫、氮的来源和酸雨成因分析;研究结果表明,形成酸雨的主要因子是SO2-、NO3-,酸雨的形成受SO42-、NO3-的共同作用;大气降水中硫来源与空气中SO2的来源存在较大差异,而氮来源与空气中NO2的来源相近,造成这种差异的主要原因是硫、氮在降水酸化过程的机理不同所致.The sources of sulfur and nitrogen in precipitation and the cause of Acid Rain were analyzed by using receptor model,based on the observation of atmospheric stable isotope and pollution source profiles.The results showed that the major factors causing acid rain were SO42 and NOr, the form of acid rain was depended on combined action. There were great differences between the sources of sulfur in precipitation and SO2 in the air, whereas the sources of nitrogen in precipitation were close to NO2 in the air. The difference in mechanism of precipitation acidification between sulfur and nitrogen led to these discrepancies.
