摘  要:
利用微积分方程,模拟单株立木树干材积,根据不同精度的需要,论述两种微积分方程下的材积计算公式。通过量取大量解析木圆盘断面长短轴,得出长短半轴比值。与传统方法相比,方便性强、精确度高,从而为今后活立木材积及林分蓄积的计算提供理论基础与参考依据。为各林业学科提供研究、分析森林的测算理论、方法和技术。同时,为发挥森林的多种效益、保持森林生态平衡、加强森林资源管理、合理利用等提供所需的基础数据。

摘  要:
Using calculus equation, the trunk volume of single tree was simulated. According to the needs of different precision, the volume calculation formulas under two calculus equations were discussed. By measuring a large number of long and short axes of wood disc section, the ratio of long and short half axes is obtained. Compared with the traditional method, it is convenient and accurate, which provides theoretical basis and reference for the calculation of standing tree volume and stand volume in the future. To provide theories, methods and techniques for studying and analyzing forest measurement for various forestry disciplines. At the same time, it provides the necessary basic data for exerting various benefits of forest, maintaining forest ecological balance, strengthening forest resource management and rational utilization.
