摘要:

林火蔓延是林火行为的主要表现形式。本文对各种林火蔓延的计算机模拟和可视化技术的最新研究状况和发展趋势进行综述。首先,分析林火蔓延相关数学模型的类别和特点、模型发展方向与体系形成。其次,讨论基于元胞自动机的和惠更斯原理的二维林火模拟与显示技术,以及三维虚拟林火环境构建技术。最后,就林火蔓延模拟与管理信息系统的最新发展进行概括。认为林火蔓延模拟与可视化的研究与开发除向高精度与实用化等方向发展外,今后将更注重真实感环境下的多维虚拟森林景观构建、多用户参与的快速决策能力(如协同灭火)以及网络信息服务等方面。

Abstract:

The spatial spreading is one of main behavior manners of forest fire. In this paper, some computer simulation and visualization techniques associated with forest fire spreading were reviewed. First, related mathematic model taxology and its member characteristics were analyzed with some development direction and model system formation being outlined. Then, the 2D simulation and representation methods, viz. Cellular Automata, Huygens' Principle-based and the approaches to establishing 3D virtual environment for fire spreading were analyzed. In the end, progress on simulation and management information system were outlined. As a conclusion, emphasizes and implies were presented that future research may make more efforts in multi-dimension virtual forest landscape with realistic sense, multi-users crisis solution decision-making capability (for example, collaborative fire fighting) and web-based dynamic information services.
