Study on the forest fire danger forecast in Yunnan Province based on GIS and RS

This paper discussed forest fire danger prediction model based on GIS and Remote Sensing in Yunnan.Rates of various vegetation flammability,vegetation dryness degree and forecast rates of weather forest fire danger were selected as the main factors of forest fire danger forecast,which were corresponding to the conditions of fuel and climate.The multifactor forest fire danger forecast index was obtained by the method of factor-weight spatial overlay,which was classified to 5 levels:non,low,mid,high and extreme high.The result showed that:multifactor forest fire prediction provided more details of the forest fire risk spatial distribution and more accordable with actual status than that only based on meteorological conditions before,and met the demand of forest fire control.
