本文系统研究了马尾松人工林地上部分生物量结构规律。提出了马尾松地上部分生物量与胸径和树高关系的数学模型W_干=6.3891+138.4515D~2H、W_枝=21.7006—90.5257D~2H+183.5857(D~2H)~2、W_叶=1.6403+16.5500(D~2H)~2、W_总=35.3710+209.2233(D~2H)~2和叶面积与叶鲜重将的关系S_叶=3.8407+9.0774W_叶,优势木和平均木地上部分干、枝、叶生物量的比例和垂直分布规律。同时还指出了土层厚度和母岩是影响马尾松生长的主要因子;马尾松林的最适叶面积指数为13—14。
This paper systematically studied the biomass of Pinus massoniana plantation aboveground biomass structure. The mathematical model of the relationship between aboveground biomass of Pinus massoniana and the diameter at breast height and the height of tree height was proposed. W_ dry = 6.3891 + 138.4515D ~ 2H, W_ branch = 21.7006-90.5257D ~ 2H + 183.5857 (D~2H) ~ 2, W_ The relationship between leaf area and fresh weight of leaves was: S leaf = 3.8407 + 9.0774W_leaf, dominance wood (leaf) = 1.6403 + 16.5500 (D ~ 2H) ~ 2, W_total = 35.3710 + 209.2233 And the proportion and vertical distribution of dry biomass, shoot biomass and leaf biomass in the above-ground part of wood. At the same time, it is also pointed out that the thickness of the soil layer and the parent rock are the main factors affecting the growth of Pinus massoniana. The optimum leaf area index of Pinus massoniana forest is 13-14.
