Abstract: Geomorphology is one of the most basic elements in geographic environments. Geomorphologic mapping is significant in representing landforms in space distribution. It helps to understand the various features of geomorphologic conditions.The task of compiling 1:1,000,000 national geomorphologic map is to enhance the study of land resources and agricultural regionalization. This paper discusses several problems in designing such a map.1. Geomorphologic classification and legend system. The legend system mainly includes five levels:a. With base colours for representing the cartographic unit of geomorphologie form of originb. Form symbols of earth surface texturec. Symbols of rock compositiond. Symbols and annotation of chronologye. Symbols of base map2. Some principles for representation of geomorphologic map.The purpose of geomorphologie map is to represent earth surface form. Therefore, images of geomorphologic features in cartographic area should be first of all considered. Then secondly, the original state system; and thirdly, the representation of geomorphologic map.3. Compiling techniques.Apart from conventional method, we considered that the analysis of remote sensing imagries and computer-aid-cartography should be applied, for it can improving mapping quality and enhance the efficiency of mapping greatly.
