Abstract: Morphology is one of the most important natural environment factors.With the development of GIS and RS techniques,Quantitative Morphologic Analysis advanced quickly.As an effective tool for Geo-science study,Geo-informatic Tupu has been applied widely in different aspects related subjects with spatial and temporal analysis.In this paper,Longitudinal Range-Gorge Region was selected as a study area since its special geographic character.Based on digital elevation model (DEM) data,image data and other geographic information of the study area,a series of Morphological Geo-informatic Tupu of different latitude transects were distilled and plotted supported by GIS and RS technique.Morphological character of Longitudinal Range-Gorge Region has been analysis.The primary result show that:In general,in Longitudinal Range-Gorge Region wave range of morphology changes largely,“V” canyon cuts deeply,slope is steeply,morphological structure is complicated.Morphology has its obvious different character in different latitude transects.From north to south,hypsography descent quickly,morphology distribution shows tow ladder form.
