Abstract:
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.
Key words: forest harvesting, optimal annual forest felling volume, forest management plan
