摘要
分析望高法计算树木材积的原理、适用范围,但因为望高点可能被遮挡,以及测望高效率较低问题,尝试用树高代替望高进行求积.为此,在利用既有解析木的有效数据研究形率系列(q)和形状指数(r)的基础上,提出了直接测算望高比(B)的方法,解决了测望高(hR)较为困难及效率较低的问题.
Abstract
This paper analyzed the calculation principle and applicable scope of tree volume by Pressler method,and attempted to use the tree height method instead of Pressler method due to the potential ob-struction of the height observation point and the low efficiency of the observation.Therefore,based on the study of the form quotient(q)and shape index(r)using effective data from existing analytical wood,the method for directly calculating the Pressler function(B)was proposed,which solved the problem of diffi-culty and low efficiency in measuring Pressler height(hR).
