摘　　要：本文通过对三江平原典型草甸、沼泽化草甸、沼泽３个群落的优势植物小叶章种群地上生物量及其时间序列分析。结果表明：３个群落小叶章种群地上生物的季节动态均呈单峰型，均在７月末达到极大值。其抛物线拟合效果良好。D. angustifoia is the dominant species in the typical meadow, marsh meadow and marsh communities of Sanjiang plain. According to these, this paper researched the dynamic of aboveground biomass and time sequence in D. angustifolia. The result reveals that: The seasonal dynamic of aboveground biomass in the three communities was monocurve and the maximum was in the end of July. The changing law of seasonal dynamic of aboveground biomass has been revealed by time sequence.
