森林采伐是调整森林结构、改善森林质量、提高森林功能的关键措施。科学的采伐管理是实现森林可持续经营的重要途径。当前我国森林采伐实行采伐限额管理制度,森林经营单位的年采伐限额原则上按森林经营方案确定的合理年采伐量核定。因此测算和确定合理年采伐量是经营方案编制的重要内容。以吉林省红石林业局为研究区,对森林经营单位如何科学测算和确定合理年伐量进行深入分析研究,以期在技术和方法上为森林经营单位编制森林经营方案及测算合理年采伐量提供参考。

Forest harvesting is a key measure to adjust forest structure,improve forest quality and improve forest function.Scientific harvesting management is an important way to achieve sustainable forest management.At present,forest harvesting in our country adopts the harvesting quota management system,and the annual allowable cutting quota of the management units,in principle,shall be determined according to the optimal annual forest felling volume of the forest management plan.Therefore,the calculation and determination of the optimal annual forest felling volume is the important content for drawing up the forest management plan.In this study,how to scientifically calculate and determine the optimal annual forest felling volume in the forest management unit was thoroughly investigated and analyzed in Hongshi Forestry Bureau,Jilin Province,China.The purpose of this study was to provide a reference in the technology and method for forest management units to draw up forest management plan and calculate the optimal annual forest felling volume.
