摘要: 调查被伐林木伐桩,推算林木材积,是林业生产实践中较为重大的问题。通常通过伐桩处的直径编制一元数表来计算被伐木的材积,这样存在着严重的偏差,将产生调查数据失真,将导致决策失误。充分利用伐桩的信息,建立三元变量数学模型,有利于提高森林资源调查数据的准确性和可靠性,可为相关科学决策提供比较真实的数学模型。

Abstract: Measuring felled tree stumps and wood volume is an important measure in forestry production.Usually the deviation of one-way tree volume table based on the diameter of stumps would easily cause a bias distortion for surveying data and eventually lead to mistakes for decision making.Making full use of stump information and establishment of ternary variable mathematical model help improve the accuracy and reliability of forest resources survey data,which provides a more actual mathematical model for relevant scientific decision-making.

Key words: fallen wood, wood volume, mathematical model
