基于SuperMap IS.NET的分布式森林资源管理系统的设计与实现

摘要

分析了当前GIS在林业资源管理上的应用,介绍了分布式数据库技术和Ajax网页异步交互式技术,并以SuperMap IS.NET为WebGIS的二次开发平台,采用SQL Server 2005作为后台数据库,搭建了一个科学、高效、合理的网络GIS系统框架模型.根据林业工作人员在资源管理上的应用需求,设计了整个系统的功能模型.以黑龙江省为例,运用ArcMap、SuperMap DeskPro等GIS专业软件和ENVI、ERDAS等遥感影像处理软件对数据进行处理并制作地图.创建了分布式森林资源管理系统,并讨论了其在现今林业管理中的意义.%The current application of GIS to forest resource management was analyzed. The distributed database technology and the asynchronous interactive web technology (Ajax) were also introduced. A scientific, effective and reasonable framework model for web GIS system was set up using the SQL Server 2005 as a database and the SuperMap IS.NET as a secondary development platform. A functional model for the whole system was designed according to the requirements of the application of managing resources for the forestry workers. Taking Heilongjiang Province as an example, some GIS professional software, including ArcMap, SuperMapDeskPro and remote sensing software ( ENVI, ERDAS), were used to process data and maps. Moreover, a distributed forest resource management system was established, and its significance in current forest management was discussed.
