一、计算方法林分生长过程表的编制基础建立在生长条件相同的各种年龄标准地林分因子的测定上,或建立在同—林分的长期观测上。但需要繁锁的专门性调查,使不同生长条件的林分失去数据分析与比较的可能性。林分生长过程理论研究的任务之一是寻求减轻编制生长过程表所需调查数量的途径。最理想的是,通过一次森林调查就可以根据林分过往年代的生长尽可能长期地预测未来。本文研究的计算方法,正是通过一次森林调查来确定一定林令的林分的主要因子。树高和直径的平均值
First, the calculation method Stands based on the growth of the establishment of the establishment of the same growth conditions for the determination of various age-standardized forest factors, or established in the same long-term observation of the stand. However, a cumbersome and specialized investigation is required, so as to make it impossible to analyze and compare data on the different growth conditions. One of the tasks of theoretical research on stand growth is to look for ways to reduce the number of surveys required to prepare a growth schedule. Ideally, a forest survey can predict the future as long as possible based on the past growth of the forest. The calculation method of this paper is the main factor to determine the stand of a certain order through a forest survey. Average height and diameter of the tree
