摘要

以古浪县为例，根据当地基本农田现状，运用ArcGIS10．2软件的数据处理功能，利用年度遥感监测影像数据进行有效核查比对。通过建设基本农田数据库，确定了保护目标，落实了空间位置，实现动态管理，为切实保护基本农田提供参考依据。%Taking Gulang County as an example, according to the status of basic farmland, using data processing function of ArcGIS10.2 soft-ware, effective verification and comparison was conducted based on remote sensing monitoring image data .Through establishment of the basic farmland database, the protection objective and location was determined, and dynamics management was realized, which can provide reference basis for basic farmland protection.
