潜在火行为是指林区的某一地段,在一天内如果发生林火可能表现的性状。要测算的指标是:地表可燃物单位面积上的负荷量W_0、燃烧速率V_0、火的初始蔓延速度R、火强度I、火焰长度cm,有效可燃物重量W及火烈度S。单点火险预报站每天将上述指标预测出来,通知防火指挥部,防火指挥部根据预报采取有效措施。如控制火源、重点巡逻、增加瞭望时间,安排计划火烧、火烧防火线、 Potential fire behavior refers to a section of the forest area, in the event of possible occurrence of fire traits within a day. The indicators to be measured are: the load W0, the burning rate V0, the initial fire propagation speed R, the fire intensity I, the flame length cm, the effective combustible weight W and the fire intensity S on the surface combustible material area. Single point of fire forecasting stations predict these indicators every day, notify the fire headquarters, fire headquarters to take effective measures based on the forecast. Such as controlling the source of fire, focusing patrols, an increase of hope time, plan a fire plan, fire fire line,
