火灾发生图与森林燃烧图的研制有助于了解森林火灾发生的规律,对防火和灭火设施与力量的调整,森林火险等级的划分和林火发生的预测预报等均有重要的参考价值。目前,世界护林防火比较先进的国家都研制有火灾发生图。如加拿大1973年曾研制荒火发生图,1979年又研制了安大略省林火发生图。1977年美国研制有南部地区的林火发生 The development of fire map and forest fire map can help to understand the regularity of forest fire occurrence, and has important reference value for the adjustment of fire prevention and fire extinguishing facilities and power, the classification of forest fire hazard and the prediction of forest fire occurrence. At present, fire prevention plans have been developed in countries with more advanced fire prevention in the world. Such as Canada in 1973 had developed wild fire map, in 1979 also developed a fire map of Ontario. In 1977, the United States developed a forest fire in the southern region
