Classification of Wetland Habitats and Analysis of Spontaneous Vegetation Characteristics in Herb Layer:A Case of Hefei Shibalianwei Wetland
Urban wetlands are a fundamental component of urban ecosystems,with important ecological functions and e-conomic application value.In order to explore the composition,diversity and similarity characteristics of the spontaneous plant communities in herbaceous layer in the wet habitats of Hefei Shibalianwei Wetland,22 sample plots and 110 sample quadrats were set up.The results showed that the wet habitats in Shibalianwei Wetland mainly include seven types,namely waterside,roadside,under-forest,abandoned cultivated land,under railway bridges,grassland and field edge.A total of 152 plant species belonging to 109 genera of 45 families were recorded,with Asteraceae,Poaceae and Polygonaceae being the dominant families.In terms of life forms,perennial herbaceous plants were the dominant type,accounting for 40.78％of the total species,followed by annual herbaceous plants,accounting for 33.55％;There were no significant differences in the species diversity of spontaneous vegetation in the herb layer among different wetland habitats in the Shibalianwei wet-land(P＜0.05),but with a higher community similarity.The research results provide scientific data for the management and development of the Hefei Shibalianwei wetland.
