| 中文摘要: |
| 复杂地形城市一般建立在山地、丘陵、沿海地带。复杂地形下的大气污染传输、扩散机制是一个复杂的问题。本文依据城市地形地貌将复杂地形归类为河谷地形、三面环山临海地形、盆地地形、马蹄型地形和峡口地形。结合国内外对这五类地形下城市污染物传输扩散及污染形成机制的研究成果，介绍了不同地理位置、不同复杂地形城市多尺度气流相互或交替作用的特点及其对污染传输扩散的影响，期望能够为其它复杂地形城市污染形成机制研究和大气污染防治提供一些借鉴。 |
| 英文摘要: |
| The term of the city over the complex terrain often lie in mountainous region, at foothill and in coastal area. It is a complicated issue for the mechanism of air pollution transport and diffusion over complex terrains. Here, according to the topography around the cities, the complex terrains are classified into five categories, which include the valley terrain, the costal terrain surrounded by hills on the other three sides, the basin terrain, the “U” shape terrain and the gorge terrain. On the basis of research results related to the transport and diffusion mechanisms of air pollutants over these five kinds of complex terrains, the mutual active characteristics of the multi-scale air flows and these flows’ influences on the transport and diffusion of the local air pollutants were presented in this article, in order to give some guide for research on the formation mechanisms and the prevention and control of air pollution aimed to the other polluted cities over complex terrains. |
