摘　　要：本研究以三江平原湿地典型草甸小叶章群落为研究对象,从物种丰富度、均匀度和物种多样性指数等方面探讨其季节动态规律。典型草甸小叶章群落物种丰富度在7月份最高,生态优势度指数季节动态变化呈"V"型;多样性信息指数季节动态变化呈单峰型,6月末7月初群落群落的物种多样性最高,种类之间个体分配的均匀性最大;均匀度指数季节动态变化呈线型。群落α多样性的测度指标的季节动态变化表现出一致性。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 Colamagrostis 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 Calamogrostis angustifolia community is linear. Seasonal variation of index of diversity of the community shows consistency.
