| 摘 要： | 利用郑州市国家基准气候站1994~2005年酸雨观测资料,分析研究了郑州市降水pH值的状况和变化,结果表明:郑州市近几年降水的pH值有逐年减小的趋势,pH值小于5.6的降水次数和频率有增加的趋势;从季节分布来看,降水pH值秋冬比春夏小。酸雨增强的主要原因是煤炭的高消耗排放的SO2量较大,再者是机动车废气排放增加,另外气候条件对酸雨的形成也有影响。

| Abstract: | Precipitation pH variation is analyzed,using the acid rain observations during 1994~2005 of Zhengzhou national basic station.The results indicate a slight decreasing trend in the Zhengzhou precipitation pH in recent years.The frequency of acid rain whose pH is lower than 5.6 is high.The precipitation pH is relative lower in autumn and winter than in spring and summer.The conclusion are also drawn that acid rain has relation with SO2 coming from coal-fired,vehicle exhaust pollution,and climate conditions. |
