随着人口的不断增加和经济的快速发展,粮食安全问题日益突出,而农业生产潜力可以描述某一地区的粮食生产能力,因此,研究农业生产潜力非常重要,对合理开发农业资源,指导农业生产,具有十分重要的现实意义。本研究在GIS技术、COM组件技术、插件技术等支持下,采用C#开发语言、ArcEngine开发组件、SQL Server数据库软件、ArcSDE空间数据库引擎,在Visual Studio .NET平台下设计、实现了一个集数据库管理、气象插值、农业生产潜力计算、农业生产潜力分析、农业生产潜力模型扩展、图形输出、系统管理于一体的农业生产潜力计算与分析系统。同时构建了一个具有统一坐标系统、数据格式、空间尺度,可以动态更新的农业生产潜力数据库。并以山东省为研究区,计算了山东省的农业生产潜力,分析了计算模型的合理性。系统应用结果表明,该系统可以很好地应用于农业生产潜力计算与分析,以及为农业生产潜力计算提供数据基础,且为农业生产潜力分析提供软件支持。

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.
