摘要
对保山地区降水酸度的监测分析表明，所辖５县市中有４个均出现酸性降水。酸性降水最高频率出现在春季，最低在夏季，按其频率由大到小排序依次是保山市、腾冲县、施甸县和昌宁县。酸性降水中硫酸盐所占的比重最大。
As shown by the
analysis of acidity of rainfall in Baoshan Prefecture,five counties and cities administrated by the
prefecture witness acid rainfall,with spring as the most frequent season and summer as the least
one.According to the frequency from more to less,the order is defined as Baoshan City,Tengchong
County,Shidian County and Changning County.The fact that the sulphate in the acid rainfall
accounts for the largest proportion shows that it is a typical acid pollution.
