| 摘 要： | 对郑州市1991～1999年的降水进行了分析.结果表明:①郑州市降水年均pH值都在5.6以上,不属于酸雨区,但很多年份都出现过酸雨;②郑州市降水主要是硫酸型污染,降水pH值与大气中的SO2有较强的相关性,降水pH值与其SO42-相关性不强;③降水中NO-3与大气中的NOx也有较好的相关性,降水中SO42-与大气中的SO2相关性不显著.

| Abstract: | The characteristic of precipitation during 1991～1999 in Zhengzhou was studied.The result indicated that ① The annually averaged pH value in Zhengzhou was above 5.6 showing the occurrence of acid rain in many years in Zhengzhou although it does not belong to Acid Rain Area.② Vitriolic pollution is main form of precipitation in Zhengzhou.There is close correlation between pH value in precipitation and SO2 concentration in atmosphere,but not strong correlation between pH value and SO42- concentration in precipitation.③ There is also preferable correlation between NO-3 concentration in precipitation and NOx in atmosphere. |
