林业机械化是发达林业的重要标志之一。瑞典、加拿大等林业发达国家,七十年代就已经实现了木材采运单工序机械化。我国主要林区黑龙江省,木材采运机械化程度也比较高,森工企业采运综合机械化比重达90%以上。我省木材采运机械化基础很差,解放初期仍然是砍伐靠斧头,集材靠肩头,运材靠水流,直到1958年才开始使用油锯伐 Forestry mechanization is one of the most important symbols of developed forestry. Sweden, Canada and other developed countries in forestry, the seventies have already achieved a mechanized timber pick-up process. Heilongjiang Province, the main forest area in China, also has a relatively high degree of mechanization of timber mining and transportation, and the proportion of comprehensive mechanized mining and transportation by forest industry enterprises reaches more than 90%.
