【摘要】 本文通过长春市区和郊区、四平、怀德四站,1983年6月至10月酸雨监测资料的统计人分析,给出了降水酸度的时空分布规律;给出了PH值与风向、风速、降水量、降水强度等的关系;PH值与雨水化学成分的关系;並比较了长春市区和郊区、四平、怀德雨水酸度的差异,酸雨的形成以局地污染为主。更多还原

【Abstract】 Through the statistical analysis of acid rain monitoring data in Changchun, Sipin, Huaide and the suburb of Changchun (June-Oct.1983 ) , the time-space distribution charactexisties of precipitation acidity, and the correlations between PH value and wind direction, wind speed, amount of precipitation, precipitation intensity etc., and the relationship between PH va lue and chemical composition of precipitation were obtained. In addition, the difference of acidity of rain between the city proper and the suburb in Changchun, Sipin and Huaide was compared, and found that the local pollution was the main reason for acid rain.更多还原
