| 摘 要： | 本文从城市热岛和城市逆温两个相互联系的不同侧面，分析城市低空气温的分布特征，并结合城市实际污染分布特征，讨论这种局地城市小气候效应对城市大气污染的形成以及对大气污染物扩散的影响，认为热岛效应以及由此引起的对低空温度层结和局地风场影响等的小气候效应是形成城市大气污染分布特征的主要气象原因。

| Abstract: | The distribution of the low level air temperature in city was analysed by discussing heat island and inversion.Considering the distribution of the air pollutant in city,the influence of the microclimate on the forming of air pollution and the diffusion of air pollutant was studied.It is indicated that the major meterorological factor which cause air pollution is the heat island effect in city and its impact on the structure of low level air temperature and the local wind field. |

| Keywords: | the heat island in city inversion air pollution |
