Ecological processes and ecological phenomena have their particularities in extreme arid zone. By analyzing the mode and method of expression of ecological information,its meanings andfeatures，as well as its relationships can be easily understood. By using remote sensing images including LANDSAT/ TM in the beginning of 1990s and 2000,as well as CB ERS-2/ CCD in 2005,the 4 first level types and 13 second level types of landscape type in Turpan，an extreme arid zone of China，are classified based on coupling relations in Mountainous Oasis Desert System(MODS).Meanwhile,the thematic symbol system of ecological landscape is designed by using the GIS symbol base and considering the objectivity andpracticability. The ecological information TUPU is constituted of graph and special symbols,descriptive digital parameters，and mathematic models. Under the support of ERDAS 8.5 and ArcGIS 9.0,a landscape ecology map is made.
