| 摘 要： | 利用2001～2011年酸雨和气象观测资料,对银川市的酸雨特征及其与气象条件的关系进行了分析和探讨。结果表明:银川市酸雨出现频率为2.21%,降水pH值年平均值为6.36;2008～2011年年降水pH值呈减小的趋势;酸雨只出现在夏、秋两季,其中11月酸雨出现频率最高;当风速较小、降水量中等时,出现酸雨的概率较大,并且沙尘天气会减少酸雨的出现次数。

| Abstract: | The characteristics of acid rain and its relationship with meteorological conditions in Yinchuan were analyzed and investigated according to the data of acid rain and meteorological factors during 2001~2011.The results showed that the acid rain frequency was 2.21%.The yearly average precipitation pH value was 6.36,and showed a decreasing trend from 2008 to 2011.Our data proved that acid rain only appeared in summer and autumn,and it had the highest frequency in November.Moreover,it was much easier to happen when with small speed wind and medium precipitation.However,it had lower frequency in dust weather condition. |
