Study on Forest Fire Spreading Model Based on Remote Sensing and GIS

Abstract

Based on remote sensing and meteorological data of fire occurrence area, a forest fire spread model is established by means of such algorithms as combustible information extraction, calculation of forest fire spread velocity and elliptic model. The input data include vegetation type, forest water content, forest slope and slope direction, forest combustible materials, wind speed, wind direction and other data. Through the analysis of fire spread, duration and fire intensity, this model can quickly judge the impact range, development trend and damage loss of forest fire in real time, so as to provide decision basis for fire fighting and rescue command. Taking the Oroqen Autonomous Banner of Greater Khingan Mountains as the research area, this model was used to predict and verify the fire spread range and trend.
