摘要: 针对森林空间结构分析复杂,计算量大,缺乏有效分析工具的现状,试图研建基于插件技术的森林空间结构分析系统以满足复杂多变的应用需求。采用.Net平台下的插件技术,基于C#开发语言,结合ArcGIS Engine 9.3组件开发包,建立了森林空间结构分析系统ASFSS,实现了平台 + 插件框架模式下的森林空间结构分析。用户能利用存放在Excel中的林分调查数据进行混交度、竞争指数、集聚指数分析,以及竞争关系分析和空间格局分析等。实现了基于GIS的森林空间结构的重建和可视化分析,为相关研究人员和森林经营管理者提供了方便快捷的分析工具。在该框架下,用户只需要增加或替换插件即可完成系统功能的扩展和升级,极大地提高了系统的移植性和扩展性,灵活的插件式设计为未来森林空间结构分析的升级提供了方便途径。图7参13Abstract: Regarding to complicated analysis,large computing and the status of lack of effective analysis tool,this paper try to develop plugin Analysis System of Spatial Forest Structure(ASFSS) to meet the complex application requirements. Based on plugin technology of .Net framework,C# and ArcGIS ENGINE components were combined to design and develop ASFSS,realizing forest spatial structure analysis with platform adding plugins mode. The users can use forest survey data storage in Excel to compute mixed index,competitive index,aggression index,and analysis competitive relationship and spatial pattern. This system fulfilled the reconstruction and visualization for forest spatial structure,providing a convenient support tool for relevant research and forest managers. Under this plugin mode,the users merely need to do is add or replace plugins if one wants to expand or upgrade the system,extremely improve systems portability and extensively. Flexible plugin design provides convenient way for future upgrade on spatial forest structure analysis. [Ch,7 fig. 13 ref.]
