武汉市城市地貌图的编制思想

THOUGHT OF COMPILING URBAN GEOMORPHOLOGIOAL MAPS FOR WUHAN

城市地貌图,应分两幅来完成,即城市自然地貌图和城市人为地貌图。城市自然地貌图中重点反映的内容应是,地表未固结的地貌组成物质和主要在地表以下的已固结的地貌组成物质,其自然地貌形态——成因类型应以动态的观念,以形态符号与形态示量相结合的方式,定量定位地表达在图上。城市人为地貌图应重点反映迭置在各种自然地貌类型之上的人为地貌单元。

This paper discusses the urban geomorphological mapping. We can make two kinds of map. One is the urban physical geomorphological map,another is the urban anthropic geomorphological map. The former map should stress the properties of unconsolidated and solid geomorphological materi als. All the physical landform types should be expressed on the map by symbols and quantitative fea tures,which are developing. The urban anthropic geomorphological map should stress every kinds of manmade land forms coverde on the physical leandforms.
