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。
This paper studied on the 18-year-old artifical woods of Pinus massoniana in Dawu county, Hubei province. Adopting the model W=a (D2H)b, We obtained the reliable results of the biomass of the pine plantation,the shrub lay and herb lay.
