摘　　要：通过对黑龙江省富锦市松花江下游沿江恢复湿地的植物群落调查和分类,研究其重要值、丰富度和物种多样性特征。结果表明,在31个调查样方中,共记录高等植物17科24属31种,以禾本科(Gramineae)、菊科(Compositae)和莎草科(Cyperaceae)植物为主。采用双向指示种分析方法,将31个样方划分为3种群落类型,分别为长芒野稗(Echinochloa caudate)群落、臌囊薹草(Carex schmidtii)群落、直穗薹草(Carex orthostachys)群落;优势种主要有长芒野稗、臌囊薹草、直穗薹草等、小叶章(Calamagrostis angustifolia)、菖蒲(Acorus calamus)等。在3种植物群落中,长芒野稗群落的物种丰富度和Shannon-Weiner指数都最高,直穗薹草群落的两种指数都最低;长芒野稗群落、臌囊薹草群落、直穗薹草群落的Simpson指数和Pielou均匀度指数依次减少。Based on field investigation of plant communities in the restored riparian wetlands along the downstream of Songhua River in August 2015, the important value, richness indexes and species diversity were analyzed to assess restoration results of plant communities. The results showed that 31 species were recorded,which belong to 17 families and 24 genera, and Gramineae, Compositae and Cyperaceae were dominant. The method of two-way indicator species analysis was used to classify species. The plants in 31 quadrats could be classified into 3 plant communities which were Echinochloa crusgalli community, Carex schmidtii community and Carex orthostachys community, respectively. Echinochloa crusgalli, Carex schmidtii, Carex orthostachys,Calamagrostis angustifolia and Acorus calamus were dominant species in the restored wetlands. The richness index and Shannon-Weiner index of Carex orthostachys community was the highest among 3 plant communities,while the same indices of Carex orthostachys community was the lowest. Simpson index and Pielou evenness index of Carex orthostachys community, Carex schmidtii community and Carex orthostachys community decreased by degrees.
