摘　　要：在林业领域,森林生长模型的预测结果可以提供丰富的详细信息,然而传统使用文本或统计表的方式表达模拟结果不利于结果的分析和理解。针对此问题,根据林分结构描述参数和分析内容的具体可视化需求,集成虚拟植物、可视化技术和森林径阶模型,设计了杉木人工林林分可视化模拟系统的体系结构。利用VS2008开发平台、Arc Engine与OSG图形渲染引擎,在Vis Forest原型系统的基础上,开发集成Weibull分布模型、杉木胸径与树高和冠幅的关系模型等,形成杉木人工林可视化模拟系统。系统实现了林分结构的统计分析、二维可视化和二三维一体化的可视化模拟。该系统为林分生长和林分经营管理的研究和决策提供了直观高效的表达手段和可视化分析工具。In the field of forestry, the output of forest growth models provides a wealth of detailed information that can often be difficult to analyze and perceive due to presentation either as plain text or summary tables. In this paper, based on visual demand of description parameters and analysis content of stand structure, we analyze tree height and diameter distribution rule and design the structure of visual simulation system of cunninghamia lanceolata plantation using Weibull distribution model, diameter and height model of cunninghamia lanceolata. On the basis of VisForest prototype system, VS2008 development platform, ArcEngine and OSG graphics rendering engine are used to develop visual simulation system of cunninghamia lanceolata plantations. The system has functions of the statistical analysis of stand structure and the integration of 2D and 3D visual simulation. The system provides intuitive and efficient expression means and visual analysis tools for stand growth and forest management or research.
