木材在国民经济中的地位很重要。盖房屋、开工厂、修铁路以及各种工程建筑,都要用到木材。在一些加工工业如制材、家俱、木箱、乐器等工业中,木材也是必不可少的。在伐木和第一次制材的时候,木材的利用很不完全。伐木以后,采伐迹地上留下了腐朽的大小木段、大小树枝和树皮。在锯木厂以及锯木和制材的加工过程中,又产生了木屑、鉋花等废料。解放以前,因为反动统治者不重视废材的利用问题,常常在采伐树木后把很多树皮留在林内,或者当作薪材烧掉。木材加工厂内的木屑、鉋花也大多当作燃料烧掉。这是很大的一笔浪费。解放以后,党和政府在木材的生产、利用方面,采取了很多有效的措施,尤其对于正确的采伐和造材,以及尽量利用废材,作出了不少的成绩。但是对木材的综 The status of wood in the national economy is very important. Wood is used for building houses, opening factories, building railways, and various engineering buildings. In some processing industries such as wood, furniture, wooden boxes, musical instruments and other industries, wood is also essential. The use of wood was incomplete at the time of logging and the first timbering. After logging, decayed wood blocks, large branches and bark were left on the felling ground. In the processing of sawmills and sawmills and lumber, wastes such as sawdust and shavings are produced. Before the liberation, because the reactionary rulers did not attach importance to the use of waste wood, they often kept many barks in the forest after harvesting trees, or burned them as fuel wood. Wood chips and shavings in the wood processing factory are mostly burned as fuel. This is a big waste. After the liberation, the party and the government took a lot of effective measures in the production and utilization of timber, especially for the correct harvesting and timbering, as well as making full use of waste materials, and made a lot of achievements.
