Extraction of Geomorphology Information of Beibei District in Chongqing Based on GIS

LI Jing JIA Ya-nan(College of Geographical Science,Southwest University,Chongqing 400715)  
Using the spatial analyzing function of GIS,through processing of 1∶50 000 DEM data of Beibei District in Chongqing,the topography characteristic elements such as slope,aspect,earth surface curvature,relief amplitude,etc.were extracted,then the localization expression and characteristics analysis were carried out.The quantitative general outline of localization of topography characteristic was obtained,so as to provide further information and basis for urban planning research in this district.
