| 摘 要： | 通过对酸雨观测资料和污染源资料的统计分析，并利用拉格朗日烟团模式计算表明，南宁市酸雨的频率较高，pH值较小；南宁市酸雨的来源构成以外来源为主。运用天气学诊断方法，对气象要素影响酸雨来源进行了分析，结果表明，南宁市酸雨主要受东北方污染源影响，且冬春两季的影响最大，风频及逆温对酸雨的影响较大。在上述分析的基础上，总结出近两年大气环流影响酸雨的几种类型，其中以高空槽锋面型为最多，酸雨影响程度也最严重。

| Abstract: | The observed data of acid rain and pollution source are analyzed, and the analysis shows that the frequency of Nanning acid rain is high and the pH value is low.The computational results of the Lagrange plume model indicate that the Nanning acid rain is mainly affected by external pollution sources.The synoptic diagnoses for pollution sources suggest that the Nanning acid rain is mainly affected by the NE pollution source,especially in winter and spring,and it is influenced also by wind frequency and inversion.Based on above analyses,we conclude several types of circulations affecting acid rain,among those,the upper trough-cold front type is the major one. |
