研究了长春市地貌景观的变化,并以空气污染气象学为指导,重点探讨了由于城区粗糙度的变化,导致大气边界层的改变,从而形成了城市区域特殊的温度和风场。出现了城市热岛和“静风”下的环流现象,改变了城区各部分大气环境质量。局部地区呈现出污染加重的趋势。为今后制定城市发展规划,防治大气污染提供了科学依据和对策。

This article makes a detailed study of changes in geomorphologic landscape with the guide of air pollution meteorology. The article discusses changes in the area of city for surface roughness. That leads to changes in atmospheric boundary layer that form special wind field and temperature field in the districts of the city. The phenomenon of thermal is land and calm has changed the districts of atmospheric environmental capacity for pollutants. There is a trend of worse pollution in some districts. All these provide a scientific basis and aim at policy for making plans of city’s development and measures aginst air pollution in the future.
