The correlativity between the quantity characteristics of every component and the biomass allocation of nutrition component, as well as between reproductive allocation pattern and nutrition component of V. yedoensis populations was studied at modular level. Analytical result indicated that the reproductive allocation is positively correlated with the leaf biomass distribution, while negatively correlated with the underground biomass distribution and the total plant biomass.%从构件水平研究紫花地丁种群各构件数量特征和营养构件生物量分配格局之间相关性及生殖分配格局与营养构件之间的相关性.结果显示生殖分配与叶生物量分配呈明显的正相关,与地下部分生物量分配和植株总生物量呈明显的负相关.
