Establishing Mode Steppe Soil Database In Inner Mogoalian Based On GIS

The thesis establish SOTER mode steppe database(1:5000) in Inner Mongolia,which mainly discuss fit landform indexes about the scale(1:5000).The thesis bring about elevation classification,slope classification and relief index classification basis on SOTER principle and actual circumstance of studied district.The thesis claasify autoly to Calculation based on DEM by Arcview. The thesis calculate landform based on elevation, slope and relief with Arcview.Base on these new landform indexes,landform of Baiyinxilemuchang was calculated and delineated. Through overlaying of landform,parent material and soil maps.by Aview,which get SOTER unite(including landform, slope and parent material). This text establish the steppe soil database system for realizing the soil information synthesizes, science the management.The thisrealize to the sketch with belong to the double of the sex information face the search by application database system,which make the soil information gets the fleetness, effective exploitation.This text make use of the characteristic data of database(total p,total k, valid-p and so on) to evaluate simplely about soil fatty by-AHP in Baiyingxileranch . and divide different fatty grade about different soil type.
