摘要/Abstract

摘要： 以长江上游亚高山地区冰碛物、坡积物上的原始峨嵋冷杉为研究对象,采用分形几何理论剖析了树体分枝结构.结果表明,峨嵋冷杉树冠的最大冠幅出现在树冠下部的20%处,其体积可以用圆台与圆锥来模拟,主干与侧枝分枝均长短相间排列,树冠表面积和侧枝分枝结构具有分形分布特征,分形维数分别为2.3232和1.8119,相关系数达0.99.

Abstract: Based on the theory of fractal geometry, branching patterns of primitive Abies fabri in the dark coniferous forest ecosystem at the upper reach of Yangtze River were studied. The results showed that the maximum crown width was appeared at inferior 20% of the crown height, and its volume could be simulated by the combination of a round table and a cone. The surface of the crown and their branching patterns of Abies fabri had the common typical fractal characters, the fractal dimensions (FD) were 2.3232 and 1.8119, and the correlation coefficient was 0.99.

Key words: Dark coniferous forest, Abies fabri, Crown structure, Branching pattern, Fractal dimension (FD), aquaculture ponds, copepod, potential recruitment, resting eggs, desiccation.
