建国以来,党和政府非常重视林业发展,营造了大量的人工林,尤其在南方的一些地区采用飞机播种,营造了大面积的“飞播林”。主要播种是马尾松,云南松、思茅松等。这些树种有生长快和郁闭快的特点,适于飞机播种造林,现有的飞播林大部分已郁闭成林。但是这些树种含油脂多,易燃烧,容易发生树冠大,加上飞播造林时没有考虑到防火规划,以致目前面临着火难控制、易蔓延成灾的大问题。因此,如何采取有效的 Since the founding of the People’s Republic of China, the party and the government have attached great importance to the development of forestry and have created a large number of plantations. In particular, sowing seeds by airplanes in some areas in the south has created a large-scale “aerial sowing forest.” The main sowing is masson pine, Pinus yunnanensis, Simao pine and so on. These trees have the characteristics of rapid growth and closed fast, suitable for aircraft sowing afforestation, most of the existing aerial seeding forests have closed forest. However, these species contain more oil, are more susceptible to burning and are prone to have large canopies. In addition, they did not take fire prevention planning into consideration when they planted them for aerial seeding. As a result, they are now facing major problems of fire control and spread. So how to take effective
