摘　　要：在建立农业生态环境系统的基础上,首次将农业生态环境系统、G IS二次开发技术和信息管理模式相集成,应用结构化生命周期方法设计开发了农业生态环境信息管理系统。该系统通过V B编程,应用GIS二次开发技术、EIS-GIS耦合技术、系统接口技术、数据库技术和信息管理技术等,实现了农业生态环境各子系统之间,系统数据库、属性库、指标库、图形库和模型库之间的数据共享,并且具有组合统计分析、多功能查询、过程可视化、可扩充性强等特点,为进行农业生态环境评价、预测、规划及优化决策提供数据源、技术方法和信息反馈通道。The research integrates firstly the agriculture ecological environment system,the secondary develop of GIS and the mode of information management on the basis of establishing the agriculture ecological environment system.Then we develop the agriculture ecological environment management information system applying the method of structured life period.The system applies the technique of secondary develop of GIS,EIS-GIS coupling,systematic interface,database,information management and so on through VB program.Not only achieving the data shared among the subsystem of agriculture ecological environment,and among the systemic storehouse of databases,properties,indexes,graphs and models,the system but also has the peculiarities such as statistical analysis,muti-function inquiry,course visualization and easy expansion.It can offer data source,information feedback routeway and technique to carry out the appraisement,forecast,program and optimization--decision of agricultural ecological environment.
