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=-0.173D³+2.33D²-6.09D+5.63，秆重和秆高的拟合方程为y=10.14-3.89H+0.55H²-0.02H³；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=0.000 7（DH）²+0.200 4（DH）-0.62的关系。

Abstract: 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=-0.173D³+2.33D²-6.09D+5.63, and the fitting equation of culm weight and culm height was y=10.14-3.89H+0.55H²-0.02H³, when the DBH and culm height are known, the function y=0.000 7(DH)²+0.200 4(DH)-0.62 is fitted.
