摘要
降水酸度在一定程度上反映了降水和大气的污染程度。以煤烟型城市抚顺为研究对象,分析了抚顺市区降水污染的现状及降水pH值的频率、时间、空间的分布特征,以此为城市环境治理提供参考依据。结果表明:抚顺的酸雨主要出现在10月和12月,降水污染主要受局地影响。降水月平均pH值与同期降水量有关,酸雨频率的季节分布与空气中的SO2和NOX浓度的季节分布状况相一致。
The rainwater acidity could indicate the relationship between rainwater and air pollution. The rainwater pollution situation and rainwater pH distribution characteristics in frequency, time and space in Fushun was studied in this paper, in order to provide the measurements with the urban environmental conservation. The results showed that the acid rain in Fushun mainly appeared in October and December. The rainwater pollution was influ- enced by local conditions. There was a close relationship between monthly pH distribution and monthly rainfall. And season distributions of acid rain frequency consisted with those of SO2 and NOx concentrations.
