Abstract

Abstract: It is a basic research that using remote sensing and GIS technology for surveying land resources of northwestern region in China,which will be a part of the national information system's foundation.Based on the field Investigation and requirement data precision,we determined the basis and principle forclassifying land resources and then established the classification system of land resources in northwesternregion of China.To employ the digital processing technique of remote sensing data(1:100,000)-man-computer interactive interpretation-vector map editing-GIS,we constructed a land resources database,which covers 1.3 million km2 of northwestern region of China.

Key words: remote sensing, GIS, northwestern region of China, land resources
