In this paper, based on the survey results of farmers' needs, the GIS system of crop distribution and supporting services for farmers was designed and developed. The system included human-computer interaction layer, data layer, functional layer and presentation layer, could assist farmers to find their own block points through names, coordinates, as well as the distribution information of other farmers who planted similar crops.
