中文摘要:
      削度方程在树干材积估算和森林碳汇规划中有着广泛的使用和重要的实际价值,其模拟直径、材积、干形变化准确与否直接决定了木材交易的公平和森林规划系统方案的科学性。文中系统阐述了削度建模数据获取方法,比较了削度方程的种类及优缺点,分析了削度方程的精度要素,并对未来相关研究趋势进行了预测。
英文摘要:
      Taper equation is one of the most widely used and importantly valued equation in volume estimation and carbon planning. The correctness of its emulation of the changes in diameter, volume and stem form will decide whether the timber transaction is fair and the forest planning plan is science-based. The paper systematically elaborated the data acquisition method for taper modeling, compared the types of taper equation and their merits and shortcomings, and analyzed the precision factors of taper equation. Finally, the future study of the equation was prospected.
