| 摘 要： | 通过实测膏桐(Jatropha curcas)人工林膏桐的地上和地下生物量,探讨了膏桐各器官生物量与地径、株高和地径平方乘株高(D~2H)的相关关系,并采用回归分析方法建立了不同器官的生物量回归方程,结果表明,以地径平方乘株高(D~2H)因子与叶、干枝、根和全株生物量相关关系最显著,可以用来估算膏桐人工林的生物量和碳储量. |

| Abstract: | Determination was made on above and under ground biomass of a single tree from Jatropha curcas plantation in Yunnan province. Analysis was conducted on relation among each organ biomass and basal diameter (D), tree height (H), and D~2H, and biomass equation of each organ was established by regression. The result showed that D~2H had the most evident relation with biomass of leaf, dry branch, root and the whole tree, indicating that it could estimate biomass and carbon stocks of the plantation. |
| Keywords: | Jatropha curcas biomass regression equation model |
