摘要:为了研究林火行为的预测预报及林火蔓延模拟的可视化问题 ,该文在分析了林火蔓延及其影响因子的基础之上 ,阐明了几种林火蔓延模型及其适用性 ,评述了选用不同的林火蔓延模型对实际火场的预测预报具有的重要理论意义及实用价值 ,初步分析了蔓延模型选择的 4个基本出发点 :模型的功能、模型适用的地区和植被类型、模型的假设条件、模型的检验频数等 .在假定已有蔓延模型的基础上 ,分析了国内外林火蔓延研究的发展状况 ,指出了在林火蔓延模型的基础上以地理信息系统为平台的林火蔓延模拟已成为林火行为预测预报的主要方向 。
For the purpose of study on forecasting forest fire behavior and the visualization of fire spreading simulation, the article is concentrated on analyzing different kinds of forest fire spread models and their application conditions based on setting forth some influencing factors such as fuels, topography and wind. It is referred that choosing a specified model will play an important role in forecasting the actual fire field. In screening fire spreading model, the four basic principles are put forward. Those are the function of model, the topography and fuels of model, the model's individual characteristics and the frequency of model and its testimony. It is pointed out that the focus on forest fire behavior is simulating the forest fire spreading on the GIS.
