| 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。时间序列分析准确地反映了小叶章种群地上生物量的季节动态变化规律。

| Abstract: | 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. |

| Keywords: | Aboveground biomass Seasonal dynamic Time sequence D angustifoia Population |
