摘要： 在自然地理环境中,地貌是最基本要素之一。地球的形状直接控制着地表热量的分布,而海陆的差异和山川起伏,又控制着水分与热量的重新分配。因此,在一定区域内地貌与其它自然地理要素,如气候、水文、植被、土壤等相互关系中,地貌条件往往起着重要作用。

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.
