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.

Key words: Aboveground biomass, Seasonal dynamic, Time sequence, D. angustifoia Population
