摘要: 为满足区域森林资源结构参数特别是郁闭度信息的统一管理与处理分析需求，以福建省三明市将乐县为研究区，以Landsat 8卫星的陆地成像仪（OLI）数据、外业调查的样地数据以及ASTER GDEM的高程数据为基础，选取逐步线性回归模型、向后线性回归模型与偏最小二乘模型研究郁闭度分布情况。在此基础上，结合空间数据库技术，在ArcGIS Server for.NET（ADF）平台下开发基于B/S模式的分布式森林郁闭度反演信息系统，实现基础地理信息系统操作、数据查询、模型因子计算、森林郁闭度模型实现、数据编辑与输出等功能，为三明市将乐县森林资源结构参数数据的规格化管理与共享服务提供技术支持。图6参15Abstract: With Landsa 8 OLI data, field investigation of the sample data and the ASTER GDEM elevation data as the foundation, this paper views Jiangle County, Sanming City, Fujian Province as the study area, and selects the stepwise-linear regression model, the backward-linear regression model and partial-least squares model to study the crown density distribution of the study area. On the ArcGIS Server for the. NET development （ADF） platform, this system combines with the spatial database technology, and sets up a distributed information system on forest crown density inversion which is based on B/S model, so that this system can carry out basic GIS operations, data query, the model factor calculation, forest canopy density model implementation, data editing and output functions, etc. Basically the system can meet the regional forest resources structure parameters analysis especially the unity of the crown density information management and processing requirements, and supports a platform for structural parameters, data normalization management and forest resources sharing services for Jiangle County, Sanming City.［Ch, 6 fig. 15 ref.］
