摘要 根据广州市近 2 0年来的气象资料和环境监测资料 ,分析了广州市气象因素与城市大气污染的特征及其相互关系 ,探讨了城市大气污染的扩散和变化规律。分析表明 :广州大气污染的时空分布特征与广州地处低纬度、高温、多雨、湿度大、热岛效应强、静风频率高、逆温频率高且以近地逆温为主的气象特征密切相关 ;认为要寻求有效防治大气污染的途径 ,达到保护环境的目的 ,应该通过合理的规划措施改善广州市的小气候环境。 Because the temporal and spatial distribution of atmospheric contamination is closely related to the weather factors, on the basis of climatic and air pollution data in the recent 10 years in Guangzhou, this paper has made an comprehensively analysis on the relation between weather factors and atmospheric pollution in Guangzhou. In addition, the characteristics of diffusion and temporal variety of the atmospheric pollution in the urban is discussed, meanwhile, the simple relationship between the characteristics of temporal variety of the atmospheric pollution and the characteristics of change of climatic and weather factors (wind speed and wind direction, air temperature, intensity of inversion and so on) in Guangzhou is proved. In order to reach the goal of protection urban environment form atmospheric pollution, the author think :Scientific urban planning tactics may improve urban climatic environment.
