1990年至今荒地火灾蔓延模型的回顾2:经验和准经验模型
A review of wildland fire spread modelling, 1990-present 2: Empirical and quasi-empirical models
摘要:
近年来,在计算能力和空间数据分析(地理信息系统,遥感等)的进步,导致了越来越多的尝试,以模拟蔓延和整个景观的野火行为。这一系列的审查文件努力批判性地全面审查自1990年以来开发的所有类型的地面火蔓延模型。本文回顾了经验或准经验性质的模型。这些模型完全基于实验获得的数据的统计分析,有或没有一些物理框架的基础上的关系。该系列的其他论文回顾了物理或准物理性质的模型,以及数学模拟和仿真模型。经验模型的主要关系是风速和燃油含水率与前向扩散率的关系。比较由不同的作者为这些变量选择的不同的函数关系。
英文摘要:
In recent years, advances in computational power and spatial data analysis (GIS, remote sensing, etc) have led to an increase in attempts to model the spread and behaviour of wildland fires across the landscape. This series of review papers endeavours to critically and comprehensively review all types of surface fire spread models developed since 1990. This paper reviews models of an empirical or quasi-empirical nature. These models are based solely on the statistical analysis of experimentally obtained data with or without some physical framework for the basis of the relations. Other papers in the series review models of a physical or quasi-physical nature, and mathematical analogues and simulation models. The main relations of empirical models are that of wind speed and fuel moisture content with rate of forward spread. Comparisons are made of the different functional relationships selected by various authors for these variables.
