摘要
低地竹是埃塞俄比亚主要竹资源之一,具有较高的经济价值和建材价值,中国也有少量资源,其经营管理尚未得到足够重视。以埃塞俄比亚本尚古勒-古马兹州1-3年生的低地竹林为研究对象,探究低地竹生物量的分配规律,为竹林经济和竹资源利用提供理论依据,以期借鉴指导中国该类竹产业发展。研究发现单因素条件下,低地竹胸径与秆重的回归曲线为y=-0.173D 3+2.33D 2-6.09D+5.63,秆重和秆高的拟合方程为y=10.14-3.89H+0.55H 2-0.02H 3;双因素对秆重的预测更为准确,已知胸径和秆重时,符合函数y=0.0007(DH)2+0.2004(DH)-0.62的关系。
Oxytenanthera abyssinica is one of the main bamboo resources in Ethiopia,which has high economic value and building material value.Taking 1-3 year-old Oxytenanthera abyssinica in Bengshanggul-Gumaz State as the research object,the biomass distribution was studied to provide a theoretical basis for its management and utilization.Under single factor condition,the regression curve of DBH and culm weight was y=-0.173D 3+2.33D 2-6.09D+5.63,and the fitting equation of culm weight and culm height was y=10.14-3.89H+0.55H 2-0.02H 3,when the DBH and culm height are known,the function y=0.0007(DH)2+0.2004(DH)-0.62 is fitted.
