生物防火亦称绿色防火,它是有效预防和控制森林火灾的治本措施。其机制原理是:对一定的防火区域进行科学规划设计,选择难燃和抗火的树种营造各类防火林带,将集中连片的林区割块、封边、形成闭合圈,从而起到阻火、隔火、断火的作用。生物防火是变被动式防火
Biological fire protection, also known as green fire prevention, is an effective measure to prevent and control forest fires. The mechanism of principle is: to a certain degree of fire science planning and design of the region, the choice of fire-resistant and fire-resistant tree species to create all kinds of fire-retardant forest belt will be concentrated contiguous forest block, edge, forming a closed loop, which play resistance Fire, fire, fire off the role. Biological fire protection is a passive fire
