根据广东省各地区气象条件的差异、森林面积的大小、森林火灾出现的严重程度，参照树种的分布，将全省划分为５个区域，在各区域内选若干代表站点，将代表站点所收集到的火灾样本资料分别与当地气象因子建立相关关系，获得火险等级评价指数，并根据指数的大小，预报未来各地区的火险等级，从而达到对广东各地进行林火分区预报的目的。 According to the differences of meteorological conditions, the size of forest area and the severity of forest fires in different regions of Guangdong Province, the province is divided into five regions according to the distribution of tree species. A number of representative sites are selected within each region and the representative sites are collected According to the size of the index, the level of fire danger in each area in the future is forecasted so as to achieve the purpose of forecasting forest fire area in Guangdong.
