摘　　要：针对我国森林小班林火蔓延模型信息化基础研究较薄弱的现状,以定量描述和分析小班林火蔓延为目的,在林业技术、地理信息系统技术、空间数学模型技术以及计算机信息等技术的支持下,以王正非和毛贤敏2位教授的林火蔓延模型为基础,建立基于八叉树理论的小班林火蔓延的数学模型,并在此基础上运用计算机技术与arcgis engine组件技术建立软件平台,实现小班林火蔓延的可视化模拟,揭示森林小班尺度的林火发生蔓延机理和过程,应用优化的林火蔓延模型实现林火蔓延空间预测。Regarding the unsubstantial status of informatization research on forest fire spread model of forest sub-compartment, for the purpose of quantitative description and analyzing sub-compartment forest fire spread, supported by forestry technology, geographic information systems technology, spatial mathematical model and computer information technology, and on the base of forestry fire spread model created by professor of WANG Zheng-fei and professor MAO Xian-min, the mathematical model of forest fire spread of forest sub-compartment was established based on Octree theory. Moreover, using the computer technology and arcgis engine component technology, software platform was built to achieve the visual simulation of forest fire spread, and to reveal the mechanism and process of forest fire spread. Optimized forest fire spread model was used to achieve the spatial prediction of forest fire spread .
