林业机械行业是林业系统的重要组成部分。而林业工具和刃具又是林业机械不可缺少的工作头或重要装备。林业工具刃具的开发创新,促进了林业机械的发展;而林业机械的发展,为全面实现林业建设的长远规划提供了可靠的保证。在发展林业机械的同时,必须充分注意林业工具和刃具的发展。一、我国森林资源短缺,开采过量,部分老的林区几乎无木可伐。“八五”计划明确规定“林业。积极开展植树造林绿化活动,……严格执行森林采伐限额,大力开展营林建设。”“森林工业。要坚持以营林为基础,合理采伐……加强木材综合利用,……。”因此,采伐工具的总量将有所减少。特别是大型、自行式采伐机械的发展会受到制约。这里虽然 Forestry machinery industry is an important part of the forestry system. The forestry tools and cutting tools are indispensable forestry machinery work head or important equipment. The development and innovation of forestry tools and cutting tools have promoted the development of forestry machinery. The development of forestry machinery has provided a reliable guarantee for the full realization of the long-term planning of forestry construction. In the development of forestry machinery, must pay full attention to the development of forestry tools and cutting tools. First, there is a shortage of forest resources and over-exploitation in our country. Some of the old forest areas are almost inedible. The “Eighth Five-Year Plan” clearly stipulates that “forestry. Actively carry out afforestation and afforestation activities ... ... strict implementation of forest cutting quotas, vigorously carry out the construction of forest.” “Forest industry. To adhere to the silviculture-based, reasonable harvesting ... Strengthen the timber Comprehensive utilization, ... ”Therefore, the total amount of logging tools will be reduced. In particular, the development of large, self-propelled harvesting machinery is constrained. Here though
