长春市的环境地貌与城市建设

ENVIRONMENTAL GEOMORPHOLOGY AND URBAN CONSTRUCTION OF CHANGCHUN CITY

环境地貌是现代地貌学中一个新兴的部门.本文系统论述了长春市环境地貌的主要特征、区域结构及其与城区建设和发展的关系。

Taking Changchun City as an example,this paper approaches some aspects of urban environmental geomorphology researches in the plain region of the semi-humid temperate zone.The features of the landforms and the regional tex- tures are analysed with the terrain slope map,the topographic complex degree map and the urban geomorphic regional map.Meanwhile,the urban surface materials and their properties on engineering are studied.It′s concluded that disastrous geomorphological processes are seldom found except tne overflow of the Yitong River.After discussing the relations of geomorphy of Changchun City and the urban historical development,the layout of building areas,road construction,water supply and sewerage network and afforestation,the paper poins out that developing afforestation is the important measure to improve the environment in the city propers,suburbs and their contiguous areas.
