| 摘 要： | 采用样方收获法和回归分析法,对云南红河流域膏桐(Jatropha curcas)人工幼龄林的生物量和生产力进行了研究。结果表明,3 a生膏桐人工幼龄林生态系统的生物量为26.025 t.hm-2,年平均净初级生产力为10.827 t.hm-2.a-1;生物量的结构表现为:灌木、草本层干枝枯落物果实根叶。对膏桐人工幼龄林各器官生物量进行了回归分析,以地径平方乘株高(D2H)因子与叶、干枝、根和全株生物量相关关系最显著。 |

| Abstract: | Using of harvesting of sampling plots and regression analysis, biomass and productivity of Jatropha curcas plantation were estimated in the Honghe River drainage area in Yunnan Province China. The results showed that the biomass of 3-year-old plantation was 26.025 t·hm~(-2) while its net primary productivity was 10.827 t·hm~(-2)·a~(-1). The biomass at different parts of ecosystem was in order of bush and herb> stem>litter>fruit>root>leaf. The biomass was distributed in the plantations of 10～14 cm diameter classes. The regression analysis indicated that the organs biomass such as leaf, stem, root and whole plant was significantly correlated to the factor D~2H. |
