木材采运机械的配备,不同于工厂性质生产所需固定的机械设备,因采运机械的使用要依伐区自然条件之不同而异。尤其是我国土地辽阔广大,不仅有南方林区地势坡度高于北方之別,即在北方地区,也因伐区地势等自然条件、采伐方式、生产工艺及生产历史之不同,而在不同程度上存在着一定的机械化的区域性;区域性的主要因子是伐区地势坡度。根据大兴安岭、小兴安岭、完达山、长白山及牡丹江老爷岭等山脉区系、地势、伐区坡度情况,初步可将我国北方木材采运机械化作业,依区域 The equipment of timber mining machinery is different from the fixed machinery and equipment required for the factory nature production. The use of mining machinery depends on the natural conditions of the cutting area. In particular, the vast land in our country, not only the topography of the southern forest terrain is higher than the northern slope, that is, in the northern region, but also due to cutting the topography and other natural conditions, harvesting methods, production processes and production history, and to varying degrees There is a certain mechanization of the regional; regional main factor is the cutting slope gradient. According to the Daxinganling, Xiaoxing’anling, Wandashan, Changbai Mountain and Mudanjiang Laoye Ridge and other mountain ranges, terrain, cut the slope of the situation, the initial wood harvesting mechanization operations in northern China, according to the region
