| 摘 要： | 利用南阳、商丘和郑州3个观测站1992-2006年酸雨观测数据进行统计,分析其15 a来年际、季节变化特征。结果表明：1992-1995年间,3站酸雨发生频率、降水年均pH值和酸雨雨量与全年雨量比值均呈现减弱趋势,1998-2006年间均出现加强趋势,且在期末明显变强;酸雨频率1、9和12月出现高值,pH值在9-12月份出现低值;1992-2000年由南到北酸雨区域逐渐变小,2000年后由南到北、由西到东酸雨区域迅速扩大。

| Abstract: | Based on the observation data of acid rain in Nanyang,Shangqiu and Zhengzhou cities from 1992 to 2006,the interannual and seasonal change were analyzed.The results showed that the frequency of acid rain,the annual average pH value,and the ratio between the rainfall of acid rain and the annual precipitation had a weaken trend from 1992 to 1995 but a strengthen trend from 1998 to 2006,and this trend was more obvious at the ending period.The high frequency of acid rain occurred in January,September and Decembe... |
