研究降香黄檀(Dalbergia odorifera ***)人工林树冠生物量的分布特征,可以为合理的评估林分生物量和调整树冠结构提供理论依据。本研究以海南东方市林龄为10~12 a的降香黄檀人工林为研究对象,设置2种不同立地条件样地(s.(1)和s.(2)),对4.5 m以上样木截冠处理,采用分层切割法和全量称重法获取树冠层各器官生物量,建立各器官最优生物量拟合方程。结果表明:(1)冠层各器官中生物量大小顺序为裸枝>枝皮>叶片;裸枝、枝皮和冠层总生物量为s.(1)>s.(2),叶片生物量则为s.(1)s.(2)。(2)随着冠层层次的增高,s.(1)和s.(2)裸枝和枝皮生物量均呈波浪形变化,其中s.(1)表现为先增加再下降,而s.(2)则与之相反;叶片生物量整体呈先上升再下降的趋势,其中s.(1)集中分布在树冠中上层,s.(2)主要分布在下层。s.(1)较s.(2)树冠上层生长竞争更激烈,已出现冠层严重的自然稀疏,叶生物量逐渐由下层转移至中上层。(3)生物量最优拟合模型为幂函数形式,分别为树冠总生物量[y.3.904(D^(2)h.^(1.247)]、冠裸枝[y.1.901(D2h.^(1.28)]、冠枝皮[y.0.734(D2h.^(1.276)]、叶片(y.3.86D^(2.791))。
