Abstract: Based on the support of the regional crop production database and the development platform of MapInfo 5.5 system, the regional crop production management geographical information system (CPMGIS) was developed with MapBasic and VB6.0. The CPMGIS includes four subsystems named as information searching, planting division, systematic forecast and precision management subsystem, respectively. Combining regional agricultural information of crop production with actual map layout, spacial analysis and relevant modeling process were conducted. CPMGIS can be used for crop farming system designing, growth predicting, optimization of cultivation management designing and precision management plan designing. There are three result output types by map or specific map, data table and text combined with graph.
