摘要
利用广西10个酸雨观测站2003～2008年近6年及南宁、百色2个观测站点1996～2008年13年的酸雨观测资料,对广西降水酸度的空间分布特征和季节变化情况进行了统计分析。结果表明,广西10个酸雨观测站年平均pH值均<5.6,其中,有5个站年平均pH值<4.5,说明广西酸雨较为严重。降水酸性的季节变化较明显,酸雨春、冬季较夏、秋季要强。
The acid rain observation data of the ten acid rain monitoring stations in Guangxi from 2003 to 2008 and Nanning and Baise stations from 1996 to 2008 were used,temporal distribution and seasonal variation situations of precipitation acidity in Guangxi were statistical analyzed. The results showed that the average pH values of the ten acid rain monitoring stations in Guangxi were all less than 5.6,and five of them were less than 4.5,which meant the acid rain in Guangxi was serious. The seasonal changes in precipitation acidity were more obviously,and acid rain in spring and winter was stronger than in summer and autumn.
