摘要
介绍一个具有数据库、知识库、方法库与模型库 ,用于精细农业中变量施肥的决策支持系统VRF -ISDSS。系统包括农业区的基础地理信息、作物生产知识、作物生长养分需求的数学模型和分析方法。系统利用知识库的知识对决策方案进行调节和优化 ,实现了智能决策。系统是在ArcViewGIS地理信息系统平台上进行二次开发而成的 ,能够处理与分析作物生长环境参数的空间分布和作物产量的空间分布等信息 ,并能够生成相应的分布图和变量施肥处方图。能够进行精细农业变量施肥的智能决策与空间决策 ,使得本系统不同于传统的农业决策支持系统以及单纯的农业地理信息系统。VRF
This paper discusses an intelligent spatial decision support system for variable rate fertilizing of precision agriculture, VRF-ISDSS. This system is composed of database, knowledge base, method base, and model base. In this system, there are basic farming land geographic information, agronomic knowledge, crop fertilizer needing mathematics models, and data analysis methods. VRF-ISDSS realizes intelligent support by using experts' knowledge and experience in the knowledge base to adjust and optimize the solution. VRF-ISDSS is developed based on ArcView GIS. It can analyze the relationship between farming land factors' spatial variability and crop yield spatial variability. And it can generate spatial information distribution maps and prescription maps for variable rate fertilizing. Intelligent and spatial decision supporting make this system different from traditional agriculture decision support systems or basic agriculture geographic information systems. Besides decision support, VRF-ISDSS has the functions of information service, scientific calculating and so on.
