摘要
对梁山慈竹地上部分生物量的结构进行了研究,并对其各器官与胸径和竹高的相关模型进行了拟合。结果表明:梁山慈竹各器官含水率大小排列为:竹叶>竹枝>竹杆;在各器官生物量的分配中,竹杆所占比例最大,为地上部分总生物量的68%;梁山慈竹各器官生物量与胸径和竹高均有较高的相关性,其中竹杆与竹高和胸径拟合的最佳模型为:W=0.034(D2H)0.755,单株地上部分生物量拟合的最佳模型为:W=0.092(D2H)0.685。
In this paper, studies are made of the aboveground biomass structure of Dendrocalamus farinosus, and the fitted models of different organ biomass are established on the basis of the diameter at breastheight （DBH）and the height. The results have shown that： the order of moisture content of each organ was：leaf〉 branch 〉 stem. In the distribution of organ biomass, stem biomass accounts for 68%, which takes the largest proportion. The organ biomass of Dendrocalamus farinosus has a high correlation with DBH and height. The best biomass model based on DBH and height for stem is： W = 0. 034 （D2H）^0.755, and that of aboveground biomass is ： W = 0. 092 （D2H）^0. 685.
