用我国现行一元立木材积表估计林分或样地的立木材积偏差很大，而直接利用二元立木材积表，则野外实测树高的工作量又太大。本研究针对这一实际问题，提出了通过建立可变参数相对树高曲线模型，将二元立木材积表直接用于林分或样地立木材积估计的方法，其估计精度可达到接近实测树高曲线法的水平。研究提出的可变参数相对树高曲线模型结构通式为：ＲＨｉ＝。 Estimated the stand volume of stand or plot with the current one-block stand in our country, there is a big deviation. However, if we directly use the binary stand-up table, the workload of field measurement is too large. In order to solve this practical problem, this study proposes a method of estimating the timber volume of stands or plots by establishing a relative tree height curve model with variable parameters, and the estimation precision can be approached to the measured tree height The level of the curve method. The structural formula of the relative tree height curve model proposed by the research is: RHi =.
