浅谈浙江省部分城市灰霾天气的时空分布特征及防控策略

Discussion of the Space-Time Distribution Characteristics of Haze Pollution in Some Cities in Zhejiang Province and the Prevention and Control Strategies

借助50年来的灰霾天气统计数据,分析了浙江省灰霾天气时空分布特征;通过查阅相关统计数据,结合文献综述,分析了浙江省主要城市的颗粒物污染特征、水溶性离子及无机元素组成,对宁波、温州地区进行了区域大气颗粒物来源解析的研究。结果表明,浙江省灰霾天气状况日趋严重,与社会经济发展密切相关;细颗粒物已成为浙江大气颗粒物污染的主要成分。而各区域的颗粒物来源有较明显的空间差异。根据研究结果,提出了工业污染减排、城市蓝天工程、绿色交通物流及农村大气污染防治等灰霆天气防控对策。

By making use of the statistical data about haze in Zhejiang Province in recent 50 years, its space-time distribution and variation characteristics have been analysed. Based on the field monitoring data and relevant references, the pollution characteristics, water-soluble ions and inorganic element composition of atmospheric particulates were analysed; and their source apportionment in the cities of Hangzh0u, Ningbo and Wenzhou was studied. The results indicated that the haze pollution in Zhejing Province has been getting more and more serious closely related to the socio- economic development; and fine particulates have become critical components in the atmospheric particulate pollutants whilst the sources of particulates in different areas showed spatial diversity. Finally, According to the research results, measures for haze pollution control including putting forward the industrial pollution reduction, city blue sky project, green transportation logistics and rural air pollution prevention have been proposed Including.
