摘要: 利用2007年4月至2009年3月昆山市气象站酸雨监测资料和气象观测资料,采用有关数理统计方法,对昆山酸雨特征进行了初步分析。结果表明:近两年昆山酸雨频率均超过80%,年均降水pH值低于4.70,为重酸雨区,其中2008年酸雨污染较2007年进一步加剧,酸雨频率季节分布趋势为:秋季大于冬季大于春季大于夏季。酸雨的强度与风向风速、降水量及霾等气象因子均有一定相关性。

关键词: 酸雨, pH值, 气象因子

Abstract: Acid rain characteristics in Kunshan were analyzed by statistic method based on acid rain monitoring data and meteorological observation data from April 2007 to March 2009. The results indicate that acid rain frequency is more than 80% in recent two years in Kunshan. The pH value of average annual precipitation is less than 4.70 in Kunshan, so it belongs to the serious acid rain area. Acid rain pollution in 2008 is more serious than that in 2007. Acid rain frequency in autumn reaches the highest, followed in winter and spring, and it is the lowest in summer. Acid rain intensity is related to meteorological factors such as wind direction, wind speed, precipitation and haze.
