| 摘 要： | 对黄柏人工纯林伐倒样木的调查,研究表明:黄柏林木单株各器官组织的生物量与胸径(D)的平方及树高(H)的乘积(D~2H)有密切的双对数直线相关,即:w=a(D~2H)~b;11—12年生黄柏林分(密度975株/ha)的平均生物量为24.22t/ha,主要分布在8m以下层次;在同一林分中,不同生长势树体其地上部分生物量的垂直分布差异显著;不同年龄和不同胸径的树体与树皮生物量均有显著的直线相关;胸径,年龄与胸高处皮厚有显著的二元回归相关,且胸径对树皮的影响远较年龄大。

| Abstract: | A study on the felled sample trees from pure stands of Chinese corktree (Phellodendron chinense Schneid)plantations revealed the following findings and results.a) The biomass in the various tissues of an individual tree bears a close log-log rectilinear correlation with the breast-high diameter(D) squared multiplied by the height(H), i.e.W = a(D2H)b.b) The average biomass in eleven to twelve year old stands where the density is 975 trees per hectare amounts to 24.22 t/ha.c) The biomass and growth of the different Organs of each tree, and the quantitative distribution of the bark biomass in these organs were worked out.d) The relationship between biomass and the correlated factors were determined quantitatively. |
