Abstract

After some small special investigation, thematic map of the Tengger Desert has never been published, most only as illustrations in the monograph. Therefore preparation of Geomorphic Map of the Tengger Desert is very important, which could reflect the panorama of the Tengger Desert, and provide rich information for studying the Tengger Desert, including law of development, evolution characteristics, distribution, etc. The scale of the map is determined to be 1:400 000 on the basis of the map range, geomorphic types and the specification of printing paper. 1:250 000 topographic maps are selected as the geography base maps. With 1:100 000 topographic maps as transitional working maps, dune symbols are compiled. Thematic contents are based on the high-resolution images provided by Google Earth in some areas. The geomorphic types are classified as aeolian-deposition landform, wind-erosion landform and other landforms. Aeolian-deposition landform is key element manifested in the thematic map. According to the analysis of the landscape types of the Tengger Desert, aeolian-deposition landform can be classified into 16 types represented by symbols, their relative height represented by colors and activities represented by arrows.
