成都市雾霾成因及影响因素分析

Research on the Causes and Influencing Factors of Haze in Chengdu

近年来城市雾霾天气频发,成都市也成为受其影响的城市之一。通过对雾霾发生机制的探讨、城市变化与发展现状的分析,对雾霾形成的影响因素进行自然因素和人为因素两方面的探究。分析认为成都独特的地理、气候环境促成了雾霾频发的条件,人为经济活动形成的城市化和产业结构促使了雾霾频发的现状。结合成都经济发展方式的转变需求,认为应从减少机动车排放及培养公众环境意识、完善城市发展规划与建设标准、调整产业结构、节约能源消耗、建立区域联防联控机制等方面综合治理城市雾霾。

In recent years , smog and haze occurs frequently in Chengdu. In this paper, the occurrence mechanism of haze and urban changes and development status of Chengdu were discussed to explore decisive factors in the formation of haze in the aspects of both natural and human activities. The analysis showed that the unique geographical and climatic conditions of Chengdu contributed to the condition of frequent haze, and urbanization and the industrial structure formed by human economic activities caused the current status of haze. Considering the needs of economic transformation, this paper concluded that reducing motor vehicle emissions, improving public awareness, optimizing city construction planning, changing industrial structure, restraining energy consumption were effective measures to control urban haze in a comprehensive way.
