重新核定木材的年产量,确定企业的建设规模是总体设计工作的关键。原总体设计虽已确定了木材年产量,但其设计均末经国家审批,因此对开展“五定”的林业局,要重新以新的资源数据为基础,根据已确定的经营区,进一步研究确定采伐方式,更新方式、更新树种等因素,以林场为单位,合理计算其轮伐周期,经营周期,和合理的“一本帐”木材年产量的做法是非常必要的。 Re-verification of timber production, to determine the scale of construction of the enterprise is the key to the overall design. Although the original overall design has already determined the annual output of timber, its design is subject to the approval of the state. Therefore, it is necessary to re-examine the new “forest resources” based on the new resource data based on the identified business areas Determine the logging methods, updating methods, updating species and other factors, to the forest farm as a unit, a reasonable calculation of its rotation cycle, business cycle, and reasonable “one account” timber annual production practices are very necessary.
