Food security is a major problem relating to the development of national economy, the stability of social political situation and the solid of state power, and occupies an important position in the national security system. With a large population and a relatively less arable land area, food security has always been a top priority matter of concern for China, while the productivity of grain is the key for food security. With the increasing population and rapid economic development, food security have become increasingly prominent, so it is important to study agricultural potential productivity, because it can describe the food production capacity in a region. It is of great practical significance to exploit agricultural resources rationally and then guide the agricultural production. In this study, supported by GIS technology, COM component technology and plug-in technology, using C # as the development language, ArcEngine as the development components, SQL Server as the database software, and ArcSDE as spatial database engine, Visual Studio. NET as the development platform, we designed and implemented an agricultural potential productivity calculation and analysis system, which included the functions of database management, meteorological interpolation, calculation and analysis of agricultural potential productivity, expansion of agricultural potential productivity model, graphics output and system management. Then we built an agricultural potential productivity database with unified coordinate system, unified data format, unified spatial scale and the ability of dynamical update. In addition, we took Shandong Province as the study area, calculated the agricultural potential productivity of the province and analyzed the rationality of the calculation model. System application results showed that, the system can be well applied in the study of agricultural potential productivity calculation and analysis, for it can provide basic data and software support for agricultural potential productivity calculation and analysis.
