摘要
根据四川省10个酸雨观测站点2007年降水观测数据，对降水pH值、酸雨频率的时空分布特征进行了分析。结果表明，降水pH值的范围为3．43～9．53，最小值出现在温江、安岳的9月份，最高值出现在巴塘的7月份，四川省酸雨主要出现在夏、秋季节；酸雨频率范围为2．9％～70．3％，最小值、最高值分别出现在巴塘、西昌，其中温江、峨眉山、西昌、攀枝花、安岳酸雨频率超过了50％，酸雨污染较重；全年电导率范同为3．8～593μs·cm^-1，川中、东、南部污染重于川西北地区。
With the observed date in ten acid stations of Sichuan in 2007, temporal and spatial distribution of pH in rain, acid rain frequency were analysed. The result showed that the range of pH is from 3.43 to 9.53. The lowest pH in rain appeared in Wenjiang and Anyue in September, and the highest in Batang in July. The acid rain days mostly happened in summer and autumn. The range of acid rain frequency is from 2.9 percent to 70.3, the lowest in Batang and the highest in Xichang. Whereas Wenjiang, Emeishan, Xichang, Panzhihua and Anyue has acid rain frequency of over 50 percent. The all - year conductance is from 3.8μs·cm^-1 to,593μs·cm^-1. The pollution of the east,south and central section is more serious than the northwest of Sichuan.
