Establishment of Ecological Landscape Informatic TUPU under the Pattern of MODS

The structure and function of Mountainous-Oasis-Desert System(MODS) is the basis of understanding ecological laws and ecological process.As one of the hot spots in Geo-informatic TUPU,Informatic TUPU of ecological landscape develops a new way for pattern changes of ecological landscape of MODS in arid zone.In order to set up the informatic TUPU of mountainous landscape,oasis landscape and desert landscape,attribute data and statistic data also including the images of Landsat TM in 2000 and CBERS-02 CCD in 2005 are used,as well as the mode recognization,thematic classification and TUPU expression based on GIS.Furthermore,the attribute database is built up,based on remote sensing and DEM data and integrated with ecological landscape characteristics ecological landscape classification.Meanwhile,using thematic mapping of landscape,function of multi-data on setting up the ecological information TUPU was also bring in.As a result,the TUPU mode of ecological Landscape is designed and the spatial and temporal characteristics of MODS are analyzed based on the informatic TUPU.
