本文通过对洮河林区四个林场,设置标准地349块,调查样木1172株,经过计算分析,揭示了云、冷杉林分的结构特点和生长规律,为合理经营提供了大量可靠数据。洮河林区云、冷杉林为复层异龄林,株数按经级分布为倒 J 型曲线,树干圆满度好,数量成熟龄在120年,林分平均生长率为2.7%,林分平均年龄在80—100年之间,平均直径20厘米,属于中龄林,并编制了生长过程表及生长量、生长率表,可供生产设计时应用。 In this paper, we set up 349 standard plots and 1172 sampling woods in four forest farms in Bahe River. Through calculation and analysis, the structural characteristics and growth patterns of cloud and fir stand were revealed, which provided a great deal of reliable data for reasonable management. The results showed that the average number of mature forest was 120 years. The average growth rate of the stands was 2.7% The age of 80-100 years, with an average diameter of 20 cm, belonging to the middle-aged forest, and the preparation of the growth process and growth, growth rate table, for the production of design applications.
