【摘要】 变量施肥是精准农业的主要内容之一。本文通过与传统变量施肥方法相比较介绍了基于RS和GIS的变量施肥方法及其在系统中实现。系统是863重大行业3S应用示范—农业项目的子课题作物品质遥感监测与肥水调优栽培决策支持系统中的一部分。系统在决策支持系统中吸收了专家系统的智能决策，利用组件技术实现了遥感、地理信息系统、模型、知识之间的无缝集成，应用3S的理论与技术构建了一个智能的处方生成决策支持系统。系统以VC为主要开发工具，采用了面向对象的编程方法。以国产的组件式地理信息系统为基本平台。实践中，根据已有的模型和知识系统能较好的完成对处方的生成，并通过了中期的验收。系统的成功开发对精准农业的变量施肥具有较大的实用意义和参考价值。更多还原

【Abstract】 Variable Rate Fertilization (VRF) is one of the most important content of Precision Agriculture. Compared with traditional methods of Variable Rate Fertilization, this paper gives an introduction of a new VRF method based on RS and GIS. This system is one part of 863 demonstration project which important industry is applied with 3S ?Agriculture. It’s also named Crop Quality Monitoring &Optimized Fertilization and Irrigation Decision Support System (DSS). This system combines the idea of Expert System into DSS and makes good use of component technology to realize the seamless integration of Expert System(ES), Geographical Information System(GIS), model and export knowledge. It is also an intelligence prescription making decision support system built with theory of 3S(RS,GIS,GPS), which is developed with Visual C++ and object oriented programming based on homemade GIS platform. In fact, we can get well made prescription with this system according the existing model and knowledge. This system has passed the middle examination too. The successful development of this system can take us high practical value and referential significance about VRF of Precision Agriculture.更多还原
