摘　　要：近十几年来,各方面的学者对中国各气候区的城市热岛、城市湿度、城市风场、降水及能见度、城市发展对热环境的影响及微热环境的调节等方面都有一定的研究。但在研究应用中却存在一些根本性、基础性问题未解决。特别是中国有一半的城镇位于山区,对山地城镇的热环境和空气质量研究甚少。因此,以具有典型山地城市特征又处于亚热带气候区的重庆市为研究对象,分析山地城市的热气候特点以寻求有效的防范与治理措施,并合理利用高科技手段来规划、建设健康的生态城市。结果表明,流体计算软件CFD可以用于室外热环境的研究,通过分析可以看出重庆市周边的热环境好于重庆市中心,市中心的热环境有待改善。There are a series of city environmental problems especially in the mountain city along with the city fast development. In recent decade, many scholars have studied the urban heat island, the urban temperature, the urban wind field, the precipitation and the urban visibility etc. But the urban thermal environment has not been settled radically. All the measures have not been used in the practice. And the researches in thermal environment of the mountain cities are very few. So the authors consider Chongqing as the researching object. Chongqing is one of the typical mountain cities in the semi-tropical. Sequentially we find out the characteristic of the thermal environment in the mountain city. Further the authors seek for the measures to plan and build ecological city. They conclude that CFD can be used in the simulation of urban environment, and use the result of simulation in urban planning is possible. The thermal environment in the center of Chongqing needs to be improved.
