| Abstract: | A study was conducted to analyze species composition,changes in dominant species,plant diversity,and community similarity in the wetlands along the Lower Yellow River under different types of land use.Understory herbs in forestland,peanut field,maize field,paddy field and lakeshore wetland in beach area of the Lower Yellow River were used as the study objects.Results showed that a total of 85 plant species,belonging to 26 families and 66 genera,were recorded in the wetlands along the Lower Yellow River under different types of land use.The plant species in the forestland was the most abundant,followed by the lakeshore wetland.Except for the peanut field and the maize field,big differences in dominant species were found between different wetlands.The species diversities of understory herbs and lakeshore wetland were low,but the number of plant species in the noncropland(understory herbs and lakeshore wetland) was the most.The community structure of the peanut field and the maize field was almost the same,and the Sorenson index was 0.596.The community similarity between understory herbs and peanut field was 0.444,and that between understory herbs and maize field was 0.310.The community structure of understory herbs and paddy field differed greatly,and there was the biggest difference between lakeshore wetland and the other four communities.Land use has an important impact on species composition and diversity in the wetlands along the Lower Yellow River. |
