Taking Zhongxian conuty in Chongqing as study area,using VisualBasic6.0 combined with ArcGIS Engine,on the bases of making full analysis of agriculture production in hilly region,this paper established recommended fertilizer information system and corresponding geographical spatial database.The paper discussed the structure and functions of the system,also discussed the foundation of database and fertilization model.This paper brought forward a way to organize the terrain spatial data and the land using status spatial data based on three levels,i.e.county,town and the core demonstration area;by analyzing of each spatial data and stressing on regress analysis of 3414 experiment in the study area,the authors formed the model of fertilization.The establishment of the system realized scientific management with the relevant data of recommended fertilizer scientifically and a series of analyzing functions,also provided technical support and assistant decision to extend recommended fertilizer information.
