Abstract:

Using virtual reality technology and facing the demand of the forest management, this paper describes the principle and process for creating a virtual forest landscape and puts forward the structure and design for a forest landscape simulation system, and develops a virtual forest landscape and an information management prototype system with VC++ programming language, Arc-Object component, OpenGL graphics standard. This system achieves virtual forest creation on three different scales, which are simple tree, stand, and landscape. It also provides multiple functions such as management, query, statistics and analysis of forest type map, virtual forest landscape design, the forest growth and management simulation, forest resources files management, etc. At last, based on data gained from the experimental area, the paper gives several applied examples.

Key words: forest management, virtual forest environment, growth simulation

摘要：

利用虚拟现实技术,面向现有林业管理业务需求,描述了虚拟森林场景的创建原理及流程,提出了一种森林景观仿真系统的体系结构及设计思路。采用VC++语言、ArcObject开发组件、OpengGL图形标准,开发了C/S分布式模式的、集二维与三维于一体的虚拟森林景观模拟与管理信息原型系统。系统实现了“单木－林分－景观”3个不同尺度的虚拟森林环境构建。系统具有林相图管理 、查询、分析、统计,三维虚拟森林中的景观设计、林分生长经营模拟,森林资源档案管理等功能。最后结合示范区数据,给出应用示例。
