摘　　要：我国年均森林火灾次数多、受害面积大、扑救困难,严重影响着我国生态安全和林业发展。林灌交错区是森林火灾蔓延的快速通道,它也是导致飞火次数和火强度增加、火灾范围扩大的重要因素。研究林火交错区内可燃物载量和含水率计算、预测方法,林火蔓延机制,交错区蔓延路径和火行为模型原理,可为延缓森林火灾蔓延和森林火灾防控提供科学有效的技术支持。The average annual number of forest fires in China is high,the damaged area is large,and it is difficult to fight them,which seriously affects the ecology and forestry development in China.The forest-irrigation staggered zone is a fast route for forest fires to spread,leading to an increase in the number of flying fires and fire intensity,and an expansion of fire extent.The study on the calculation and prediction methods of combustible material load and water content in forest fire staggered zone,the mechanism of forest fire spread,the path of spread and the principle of fire behavior model in staggered zone,provides scientific and effective technical support for delaying forest fire spread and forest fire prevention and control.
