中国地域辽阔、自然条件十分复杂,人均所占森林资源水平较低,人工林和次生林所占比重较大。同时,受地理位置、气象因素、植被条件以及社会情况等影响,森林火灾比较严重。最近几年来春秋两季我国森林草原火灾也频繁发生,造成在资源和经济上的很大损失,为了尽量减少损失,迫切要求我国建立一条长效且具有战略意义的防火线。防火线是一项为阻隔森林火灾蔓延,减少损失,提高控制林火能力的重要设施。 China has a vast territory with very complicated natural conditions, with a low level of per capita forest resources and a large proportion of plantations and secondary forests. At the same time, the forest fire is more serious due to its geographical location, meteorological factors, vegetation conditions and social conditions. In recent years, the forest and grassland fires in our country have also occurred frequently in spring and autumn, resulting in great losses in resources and economy. In order to minimize the losses, it is urgent to urge our country to establish a long-term and strategic fire line. Fire line is an important facility to stop the spread of forest fires, reduce losses and improve the ability to control forest fires.
