| 摘 要： | 根据大气降水及燃煤和燃油中硫、氮稳定同位素分析,应用受体模式解析降水中硫、氮的来源;研究结果表明,形成酸雨的主要因子是SO42-、NO3-,本地人为污染源排放对酸雨的贡献为54.2%、外来污染源占45.8%;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.

| Abstract: | Based on the observation of atmospheric stable isotope and pollution source profiles.The sources of sulfur and nitrogen in precipitation were analyzed by using receptor model.The results showed that the major factors causing acid rain were SO42-and NO3-.Contribution of local artificial pollution source and allochthonous pollution source to acid rain were54.2%and 45.8%,respectively.There were great differences between the sources of sulfur in precipitation and SO2in the air,whereas the sources of nitrogen in precipitation were close to NO2in the air.The difference in mechanism of precipitation acidification between sulfur and nitrogen led to these discrepancies. |
