基于GIS的低丘缓坡林地管理系统的关键技术

在分析低丘缓坡林地管理现状的基础上，通过对低丘缓坡林地管理系统需求分析，设计并实现了低丘缓坡林地管理系统。对系统的数据流程、功能结构等进行了详细研究，分析并解决了系统设计与开发中的若干关键技术，如数据集成管理技术、报表统计查询技术、专题输出模型、三维空间分析和显示技术等。并以Visual Studio．NET和ArcGIS Engine为开发工具。实现了系统数据的集成管理、报表统计和查询、数据综合分析、专业制图和成图、空间分析处理、三维可视化结果显示等六大功能模块。图6参9

Research on key technologies of GIS-based low hilly woodland management system

On the basis of the review of the management status quo of low hilly woodlands, we analyzed the demands for the management system of low hilly woodlands, and designed a corresponding management system. We also analyzed the data process and functional structures of the system, solved some key technological problems in designing and developing the system, for example, data integrated management technique, report forms statistic and query technique, thematic map output technique, spatial analyst and 3D display technique. With the Visual Studio.NET and ArcGIS Engine as developing tools, the research realized six modules including data integrated management module, report forms statistic and query module, synthetic data analysis module, thematic map making module, spatial analyst module, and 3D display module.
