Seasonal rhythm of aboveground biomass—the Calamagrostis angustifoliagrassland in Sanjiang plain

In this paper, the seasonal rhythms of the above grassland biomass of the two main types of theCalamagrostis angustifolia grasslands, theCalamagrostis angustifolia meadow and theCalamagrostis angustifolia +Carex schmiditii swamp meadow, were reported. The simulation technique was employed to described the dynamic process. In the end, the absolute growth rate and the relative growth rate of aboveground biomass of the two communities were approached in the light of the growth analysis method.
