北京地区蔬菜病虫害远程诊治专家系统VPRDES的研究

Study on vegetable pests remote diagnosis expert system(VPRDES)

以软件工程原理和专家系统技术为基础,采用LUBAN模型和JSP编程语言,通过构建农业病虫害辅助诊治推理机,研制了北京地区蔬菜病虫害远程诊治专家系统VPRDES。VPRDES是一个针对北京地区140余种蔬菜常见病虫害进行远程辅助诊治和信息查询、管理的网络型专家系统。该系统对实时推广北京地区主要蔬菜病虫害的无公害治理技术、促进农户合理用药、提高蔬菜产品的安全性等具有重要作用。

The safety of vegetable production directly affects consumers＇ health and social stability in China. VPRDES （Vegetable Pest Remote Diagnosis Expert System） was developed in this study based on software engineering theory and expert system technology. The LUBAN module was used as the VPRDES development module and JSP as the programming language. Inference engine was constructed for assistant diagnosis of agricultural pests. VPRDES is a network expert system, which offers functions of remote diagnosis, information inquiry and manage ment of 142 common vegetable pests in Beijing area. This system has significant influence on the popularization of public hazard free technology in vegetable pests management, the improvement of farmers＇ skills in pesticide application and the promotion of the safety of vegetable products.
