A NORMAL YIELD TABLE FOR LARIX GMELINII INDAXIN GANLING BASED ON THE MAXIMUM GROWTH RATE METHOD

Normal yield tables for Larix gmelimii(Rupr) Rupr were constructed from 228 tem-porary sample plois.A normal stand was defined as having the maximum growh rate parameter,based on the theory of forest growth.Basal area growth curves were described with Richard’s equa-tion according to Von-Bertalanfy’s growth theory and allometric law.The growth rate parameterwas found to be K,so a normal stand had maximum K.Thus the basal area growth curve of a nor-mal stand was obtaied simply by increasing K.A normal yield table for L.gmelinii of Daxinganlingnatural forest was then constructed.

正常收获表的研制

本文利用兴安落叶松幼、中龄林一般临时样地材料,研究了正常收获表的编制方法。根据森林生长理论,把正常林分定义为“生长模型中生长率系数最大的林分”。又根据Von Bertalanffy生长理论和相对生长法则,用理查德生长方程描述林分断面积的生长曲线。从而导出的系数k是生长率参数。由定义正常林分可视为k值最大的林分,所以提高k值可求正常林分断面积生长曲线,编制出正常收获表。
