摘要
本文通过对三江平原典型草甸、沼泽化草甸及沼泽群落的优势种群—小叶章种群地上生物量生长量及其时间序列的分析表明：典型草甸小叶章种群地上生物量生长量季节动态呈“Ｗ”型。另两个类型呈双峰型。其累积生长量均呈单峰型，且在整个生长季，干物质均有一定程度的积累，时间序列分析也验证了上述变化趋势。
D. angustifoia is the dominant species in the typical meadow, marsh meadow and marsh communities of Sangjinag plain. Acccording to these, in this paper we researched the dynamic of aboveground biomass and time sequence in D. angustifoia. The result reveals that: the seasonal dynamic of density in marsh was 'W' curve; the seasonal dynamic of density in typical meadow and marsh meadow was bimodal curve; the accumulation biomass was monocurve. In whole growing season, dry-matter has been accumulated. The changing law of seasonal dynamic of aboveground biomass has been revealed by time sequence.
