Abstract: The Series thematic maps of desertification are the main data sourcein the Information System for Environmental Monitoring of Desertification,and provide the fundamental bases for the special munipulatium and analysis. According to the used computer aided mapping software. Some problems of editing and mapping of thematic maps in the system has been discussed in this paper mainly including as following:(1)Disigning the thematic maps used in the information system for desentification environmental monitoring:(2)Mapping classification of the thematic maps; (3)Unification and coordination of the series thematic maps in the system : (4) Editing features of the series gyematic maps of desertification; (5) time sequemes of the map in desertification environmental monitoring.
