摘要:

根据南宁市环保监测站的酸雨监测资料和南宁市气象局的气象观测资料,分析南宁市本地污染源排放、大气颗粒物缓冲能力、大气中H₂O₂含量以及气象因素对南宁市酸雨的影响,提出南宁市的自然地理环境和气象气候条件有利于酸雨的形成,其形成与冷空气关系密切;影响南宁市的大气环流主要是东路、中路冷空气,这两股冷空气南下时容易形成酸雨且降水酸性明显增强。南宁市的酸雨受外来的影响非常明显

Abstract:

The influences of local pollutant emission,particulate buffering capacity,concentration of H₂O₂ and weather factors on acid rain formation in Nanning city are discussed according to the record data of Nanning Environmant Inspection Station and Nanning Weather Bureau.It is showed that the physical geography circumstances and weather conditions of Nanning are favorable to the formation of acid rain. The formation of acid rain shows a close relationship with northern cold atmosphere.The acidity of precipitation increases markedly when the eastern and middle coldatmospheres pass through from the north.The acidity of Nanning is affected by external influence remarkably.
