以气象因子、土壤特性、品种参数、生产条件等数据为农作信息依托,以具有时空适应性的作物栽培管理动态知识模型为管理决策支撑,以网络通讯为系统信息发布与流通平台,运用软构件技术与Web应用技术,设计和实现了基于浏览器/服务器(B/S)模式的具有4层分布结构的网络化作物管理决策支持系统(knowledge model and web-based deci-sion support system for cmpmanagement,KMWDSSCM)。以江苏省为案例区,对系统进行了示范应用,结果表明,系统能在Internet环境下有效地进行作物生产管理决策,在江苏部分地区稻麦生产实践中具有较好的适用性和指导性。
Based on the data of variety, weather, soil, production condition etc. and knowledge model and the four layers web structure of “Web browser/Web server/Application server/Database server”, a knowledge model and web-based decision support system for crop management (KMWDSSCM) was developed by using the engineering and technique of the software component and web application. Case studies on KMWDSSCM with the datasets in Jiangsu Province indicated that the system could be effectively applied for crop management and decision support under the web service environment, and showed a good applicability and guidance on rice and wheat production at some areas of Jiangsu.
