| 摘要: |
| 小飞蓬是我国分布最广的外来入侵物种之一,通过样方调查,从构件水平研究了小飞蓬各构件的结构特征及其生物量间的关系模型,并进行了定量分析。结果表明小飞蓬各构件生物量间的关系表现为茎>叶>根>花; 各构件生物量在个体生物量中所占比率也表现为茎>叶>根>花; 小飞蓬根、茎、叶生物量与植株高度及各构件生物量间均呈正相关关系。 |

| Abstract: |
| Conyza canadensis is one of the alien invasive plants distributed most expensively in China. Biomass structure characteristic and correlation models among different modules of Conyza canadensis population were studied at module level. Their quantitative analysis was also done in this paper. The result showed that the modules biomass of Conyza canadensis was decreased in the sequence of stem,leaf,root,flower,and the biomass proportion of each module to the whole plant biomass was also in the same order with modules biomass. The biomass of root,stem and leaf had significant positive correlations with plant height,and the biomass of each module had significant positive correlation with that of others,too. |
