摘    要:对耐寒丛生竹种椽竹Bambusa textilis var. tasca 种群的生物量结构进行了研究,并对其各器官生物量与胸径和平均壁厚的相关模型进行了拟合。结果表明:椽竹各器官生物量的分配中,竹秆所占比例最大,为总生物量的74.62%,远超过毛竹Phyllostachys pubescens等竹种的相应值。椽竹的胸径和平均壁厚与各器官生物量之间均呈极显著相关性,其中竹枝生物量干质量(Bt),竹叶生物量干质量(Bf),竹秆生物量干质量(Bs),地上部分生物量干质量(Ba),全竹生物量干质量(Wbt)与胸径(D)和平均壁厚(A)间相关关系的拟合模型分别Bt = - 2 672.765 + 1 299.919D + 59.298D2 - 36.222D3Bf = - 2 756.615 + 1 290.910D + 95.822D2 - 34.991D3Bs = - 4 016.535 + 2 161.650D + 21.755D2 - 45.453D3Ba = - 7 445.916 + 3 952.480D + 45.439D2 - 96.666D3Wbt = - 7 360.122 + 3 933.155D + 41.158D2 - 93.171D3Bt = - 1 914.129 + 739.465A + 30.261A2 - 61.285A3Bf = - 3 342.800 + 1 228.745A - 1.165A2 - 104.356A3Bs = - 6 103.838 + 1 790.994A + 44.430A2 - 13.674A3Ba = - 9 770.036 + 2 464.708A + 19.688A2 - 23.782A3Wbt = - 9 914.842 + 2 912.175A + 25.624A2 - 23.513A3。根据以上公式估算出椽竹林单株平均秆生物量为1.52 kg·株-1,单株平均全竹生物量2.31 kg·株-1,单位面积秆生物量3.28 kg·m-2;单位面积全竹生物量4.96 kg·m-2。表8参29

Abstract:The biomass of Bambusa textilis var.tasca was studied using regression models that were constructed for biomass components:bamboo pole-dry(Bt),bamboo leaf-dry(Bf),bamboo culm-dry(Bs),aboveground part-dry(Ba),and bamboo-dry(Wbt);based on diameter at breast-high(DBH)(D)and the average thickness of the culm-base(A).For the purpose of Bambusa textilis var.tasca rational operation and development to provide theoretical basis and basic data.Results showed that culm biomass of B.textilis var.tasca counted for 74.6...
