In this study, using the Sanjiang Plain Wetlands typical meadow Calamagrostis angustifolia community as the research object, explores the evenness and diversity index, the seasonal dynamics of species richness of it. Species richness of the typical meadow Calamagrostis angustifolia community is the highest in July, seasonal dynamic change degree index of ecological advan-tages in“V” type; diversity index seasonal change of single-peak type. At the end of June to early July, community has the highest species diversity, distribution of individual species between the maximum uniformity; The seasonal dynamics of evenness index of typical meadow Calamagrostis angustifolia community is linear. Seasonal variation of index of diversity of the community shows consistency.
