摘　　要：根据浙江省近50年的灰霾天气统计数据,总结了浙江省灰霾天气特征。以杭州市为例,从杭州市地形地貌、气候因素和污染物排放因素3方面分析了杭州市灰霾天气成因,介绍了杭州市大气颗粒物污染特征及源解析。结果表明,杭州市灰霾天气频率显著升高,污染物排放是导致灰霾天气发生频率升高的直接原因,杭州市大气颗粒物中以细微颗粒物为主,大气污染类型已从煤烟型污染转变成复合型污染。结合杭州市大气污染现状,初步提出了灰霾天气防控对策。Based on the meteorological statistical data of haze in recent 50 years, the eharacteristies of haze pollution in Zhejiang were summarized. Take Hangzhou as example, the paper analyzed the cause of haze pollution in Hangzhou from 3 aspects of climate, landform and pollutant emission. The characteristics of atmospheric particulates pollution and the genesis of haze pollution in Hangzhou were introduced. The results indicated that the frequency of haze occurrence was significantly increased in recent years, and it was closely related with the socioeconomic development; the proportion of the fine particulate was quite high in atmospheric particulates. Depend on the results, the primary measurements for haze pollution controls were proposed.
