摘　　要：对杭州市1998年—2002年的降水监测数据进行了统计分析。结果表明,2002年杭州市区酸雨频率为73.6%,降水pH均值为4.68,临安酸雨频率高达97.5%,降水pH均值为4.04,其余几个县(市)降水酸度均<5.60。杭州市有82.1%面积属重酸雨区。指出,杭州市气象条件不利于大气中SO2、NOx的扩散,土壤扬尘不能对酸雨的形成起有效的缓冲作用,因此只有通过调整能源结构,从源头控制煤质(含硫量),严格控制机动车尾气污染,以减少SO2、NOx排放量。Statistic was done for the precipitation monitoring data of Hangzhou from 1998 to 2002. In 2002, the frequency of acid rain was 73.6%, pH was 4.68. In Linan, the frequency was up to (97.5%,) pH was 4.04. In other region, pH was less 5.60. There are 82.1% area of Hangzhou was heavy pollution area of acid rain. The meteorological condition of Hangzhou was bad for the dispersion of SO_2?NO_x in atmosphere. It must adjust energy structure, control the sulfur content in coal, and control the emission pollution of motor vehicle, to decrease the emission of SO_2?NO_x.
