摘要
探讨了南京浦口区春季酸性降水的局地特征,得到了一些有意义的结果。就春季平均降水酸度来看,整个地区降水普遍呈酸性,降水的酸度分布是城区大于郊区,降水的SO_4^(2-)浓度占总阴离子浓度的69.8%~76.1%,占总离子浓度(阴、阳离子浓度之和)的36%~43%。反映了本地区能源结构以煤为主,煤烟型污染是本地区大气污染的主要特征。
Through the study of acid rain for parts of an area, some significative results are obtained. The precipitation of all areas emerges generally acidity as seen by the average precipitation acidity in spring. The average precipitation acidity distribution in urban district is more than that in rural district. SO42- concentration is from 69.8% to 76.1% in all negative ions' concentration and from 36% to 46% in all ions (It means total positive ions and negative ions in the precipitation). The result shows that coal is a major resource of energy. Air pollution mainly results from coal combustion in spring in pukou, Nanjing,
