摘　　要：目的近年来地理信息行业飞速发展,随着遥感技术的应用及国家对遥感技术民用化的支持。地理信息系统在各级政府主管部门林业、农业、水利等资源管理方面得到广泛的应用。介绍了林业资源管理系统的模型-视图-控制器(MVC)设计模式,通过林业资源管理平台实现分布式土地管理系统。方法使用MVC架构,通过集成网络地理信息系统(GIS)和管理信息系统(MIS)形成一个统一的网络环境。结果平台实现了对林地变化和不同的部门出具的机构报告、调查以及不同的政策和要求的功能,同时网络系统中的独立分区平台保证了界面与用户交互的功能和整个系统灵活、稳定。结论分布式管理系统利用监测平台的集成与MVC基础设施分区,可以在改变不同的后端流程时无需修改其他进程和应用程序,从而减轻对不可预知和复杂的分布式系统环境的影响。Objective With the development of remote sensing technology and support of the remote sensing technology in China,the geographic information industry has developed rapidly.The application of GIS has been widely used in the manageement of forestry,agriculture,water resources and other departments of government at all levels.The design model of model view controller(MVC)of forestry resource management system was introduced and realizes the distributed land management system was realized through Langfang forestry resource management platform.Methods By taking Langfang city as the research area,and using MVC framework,the integration of network geographic information system(GIS)and management information system(MIS)was carried out to form a unified network environment.Results The platform implemented the functions of institutional reporting,investigation,and different policies and requirements issued by different departments.At the same time,the independent parition platform in the network system ensured the interaction between the intertace and the user,and flexibility and stability of the whole system.Conclusion The distributed management system uses the integration of monitoring platform and MVC infrastructure partition and modifies the different back-end processes without modifying other processes and applications,thus reducing the impact of unpredictable and complex distributes system environment.
