潜在森林火险评估方法研究--以山东省为例
Research on the Evaluation Method of Potential Forest Fire---Taking Shandong Province as an Example
摘要
Abstract
Forest fire risk map plays a very important role in the management and research (watchtowers,risk assessment and various other simulations)on forest fire.According to full consideration on fire probability of fire-causing factors (constants and variables),integrated fire danger index are composed by using remote sensing (RS) data and static and dynamic index generated from spatial analysis characteristics of geographic information system (GIS).The most important 10 factors of fire are average surface temperature,near ground air humidity ratio,vege-tation type,vegetation coverage,altitude,slope,slope direction and distance from residents,distances from roads, population quality.Static fire danger index take those factors into study.By using fire potential index model of the United States and MODIS data,land surface temperature,air humidity,vegetation humidity data,etc are got from dynamic fire hazard index to obtain moisture of died and living fuel.Verification is done to 132 fire points in 2011. Results show that the integrated fire danger index occupies 82.6%above the extremely high range,which indicate that it is quite important in potential fire application.关键词
