蔬菜安全生产管理与服务网络平台设计及实现

为了进一步推进蔬菜生产的安全化、信息化和现代化，促进蔬菜安全生产，该文以国家综合示范项目为基点，以国家蔬菜生产基地——寿光的专业数据为例，综合采用J2EE（Java2平台企业版,Java2 Platform-Enterprise Edition）技术、地理信息系统技术（GIS）、网络技术（Internet）、无线通讯技术、数据库技术（DBMS）以及可移动电话或手机GPS定位技术，研究、设计和建设了蔬菜安全生产管理与服务网络平台，包括基于WebGIS的蔬菜安全生产有线网络系统、基于GIS与无线通讯的氮肥平衡推荐系统和基于3DGIS的蔬菜安全生产可视化系统。该平台能够辅助政府机构实时对蔬菜的安全生产进行监控，提供决策依据，为蔬菜生产用户提供氮肥平衡推荐和蔬菜栽培技术指导，并将氮肥平衡推荐功能扩展到低端硬件手机用户，实现生产信息技术到田间地头的延伸。

Design and implementation of management and service network platform in vegetable safety production

For furthering the safety and information and modernization of vegetable production, and promoting vegetable safety production, based on the comprehensive national demonstration projects and as an example of state-level vegetable production zone--Shouguang, the management and service network platform of vegetable safety production was designed and developed by full utilizing the technologies of J2EE, GIS, internet, wireless communication, DBMS and mobile phone or GPS. The platform involved the cable network system of vegetable safety production based on WebGIS, the recommended nitrogen balance system based on GIS and wireless communication, and the visualization system of vegetable safety production based on 3DGIS. Through the platform, government departments could real-time monitor vegetable safety production and provide the basis for decision-making. Vegetable producers could be offered with the recommended nitrogen and cultivation techniques, morover, the recommended nitrogen balance system was expanded to low-end hardware mobile phone, which achieved the extension of production information techniques to fields.
