内蒙古大兴安岭是我国的主要林区之一,年生产商品材约350万m~3,平均年采伐面积4.6万公顷,可提供能利用的伐区剩余物4.58万m~3,相当于两个中型林业局的年产量。这些剩余物由于利用率低下,大部分被遗弃在采伐迹地内,任其自然腐朽,不但影响森林更新,而且使森林卫生环境恶化。充分利用森林资源,减少采伐面积,为造纸和人造板工业提供原料,伐区剩余物的利用是林业生产中急待解决的问题。
Daxinganling, Inner Mongolia is one of the main forest areas in China with an annual output of about 3.5 million m 3 of products and an average annual harvest area of 46,000 hectares. It can provide 45,800 m 3 of usable cutting area, equivalent to two medium-sized Forestry Bureau of the annual output. Most of these residues, which have been abandoned in deforestation due to their low utilization rate, have naturally decayed them, not only affecting the renewal of forests but also deteriorating the forest sanitation environment. Making full use of forest resources, reducing harvesting area, providing raw materials for papermaking and wood-based panel industry, utilization of surplus area in cutting area is an urgent problem in forestry production.
