摘要: 应用遥感和地理信息系统(GIS)技术开展西北地区土地资源动态调查是建立国家级基本资源遥感动态信息系统的一项基础性工作。在这项工作中,我们首先在确定土地资源分类依据和原则的基础上,建立了西北地区土地资源的分类系统;通过遥感数据一人机交互解译一矢量图编辑一地理信息系统的全数字方式,完成了90年代中期由1:10万基本数据支持的西北地区土地资源信息系统数据库的建设。

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
