摘　　要：为了进行“精细农业”实践，以土壤耕作阻力的测量为例，通过ＤＧＰＳ后处理定位技术，研制开发了农田ＧＩＳ属性数据库数据源获取的硬件系统和软件支持。形成了土壤不同深度层的耕作阻力分布图。The development of Differential Global Positioning System(DGPS), GIS & Decision Support System(DSS) provide the technological support for Precision Agriculture(PA). To carry out the practice of presision agriculture, taking the measurement of the soil tillage resistance as an example, the method to form the source of the GIS characterization database by using post DGPS technology was studied in this paper. The distribution maps of the mechanical strength of different depth of the farmland were drawn.
