摘 要: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。The construction of normal yield table was studied with information of temporary sample plots of Larix gmelinii Rupr. The normal stand was defined as 'the stand which had maximum growth rate parameter' based on theory of forest growth. Basal area growth curve could be described with Richa(?)ds equation according to Von Bertalanffy's growth theory and allometric law. It could be also derived that K was the growth rate parameter, So normal stand was one which had maximum K. Thus basal area growth curve of normal stand could be easily obtained by increasing K and normal yield table was constructed.
