摘　　要：为探究早春植物附地菜种群构件水平上的生长特征,更深入地了解其在不同生境下的生存策略及环境适应性,本研究通过野外调查取样和室内分析的方法,对林下和路旁两个生境下附地菜植株生物量分配特征、异速生长关系及其不同生境间的差异进行研究。结果表明,附地菜植株在两种生境下均有较高的变异系数,其增长规律呈幂函数增长或线性正相关,附地菜在不同生境下具有显著的资源分配形式。In order to explore the growth characteristics of Trigonotis peduncularis population at the component level in early spring,and to better understand its survival strategy and environmental adaptability in different habitats,this study was conducted by means of field investigation,sampling and indoor analysis.The characteristics of plant biomass allocation,allometric growth and the differences among different habitats such as understory and road side were studied.The results showed that the plant had a higher coefficient of variation in the two habitats,and its growth law was a power function or linear positive correlation,and it had a significant form of resource allocation in different habitats,which provided a theoretical basis for its resource utilization.
