| 摘 要： | 本文对大悟县18年生的人工马尾松(pinus massoniana Lamb.)林设置样方,应用树干重(W.)=0.9815(D~2H)~(0.4759);枝条重(W_(br))=0.9852(D~2H)~(0.2525),叶重(W_i)=0.9825(D~2H)~(0.1532)和根系重(w_r)=0.9747(D~2H)~(0.1829)幂函数方程,分别估算出树干、枝条、叶和根的干重。马尾松总生物量为92.51t/ha,树干、枝条、叶和根器官的干重分别占59.68％、17.89％、10.62％和11.8％。采用直接收割法获得灌木层和草本层的总干重为5.6t/ha。人工马尾松林总生物量为98.11t/ha。
