对历史火灾严重程度模式的分析提供了在被当代森林管理实践(如伐木、筑路、放牧和灭火)改变之前的火灾制度的观点。历史火灾数据可以将当代观测到的火灾数据置于更长的时间背景下,并建立先验可能性,以测试预测火灾行为和森林植被模拟模型的输出。当与生物物理和遥感数据相结合时,火灾历史数据已被建模,以创建粗比例尺(1平方公里,Schmidt等人,2002年)和精细比例尺(30平方米,Rollins和Frame, 2006年)美国相邻地区的火灾状况地图(LANDFIRE, 2007年)。
Analysis of historical fire patterns of severity provides a view of fire regimes before they were altered by contemporary forest management practices such as logging, road-building, grazing, and fire suppression. Historical fire data can place contemporary observed fire data in a longer temporal context, and establish prior likelihoods to test outputs from predictive fire behavior and forest vegetation simulation models. When integrated with biophysical and remote-sensing data, fire-history data have been modeled to create both coarse scale (1 km2, Schmidt et al. 2002) and fine scale (30 m2, Rollins and Frame 2006) maps of fire regimes for the contiguous United States (LANDFIRE 2007).
