| 摘 要： | 采用标准样方法研究了杂交竹各器官及不同龄级生物量配置,结果表明:①杂交竹单株平均生物量为5.0116 kg,林分平均生物量为34.1794 t.hm-2;②杂交竹单株和林分各器官生物量从高到低都表现为竹杆竹枝竹叶竹蔸竹根;③不同年龄杂交竹单株生物量大小排序为3 a2 a1 a,林分生物量表现为2 a1 a3 a;④杂交竹竹枝、竹杆、竹叶及全株以幂函数(W=cDaHb)为最优生物量模型,竹蔸、竹根则以多项式(W=c+aD+bH)为最优生物量模型。

| Abstract: | The biomass characteristics of hybrid bamboo among organs in different ages were measured by means of sample plot.The results showed that: the average biomass of per plant was 5.0116 kg,and the biomass of each organs order was as follows: trunk>branch>leaf>underground truck>root.Biomass of per plant in 1 to 3 age order was 3 a>2 a>1 a,but the stand biomass was 1 a>3 a>2 a.The classic biomass model of hybrid Bamboo in branch and trunk and leaf was the power function models(W=cDaHb),and underground truck and root classic biomass model was the polynomial(W=c+aD+bH). |
