Its purpose is to restore the ecosystem services and biodiversity of the natural wetlands that modified by human development, of wetlands. In the past, restoring wetlands often emphasize on increasing wetland heterogeneity. However, it has seldom been studied whether species diversity can be increased by restoring diverse types of wetlands. In this study, the wetlands at the Qigu Campus of NUTN was restored by increasing the hydrological conditions of wetlands and ceasing the operations of the fish farms. After about 10 years of natural succession, the wetland of various habitat types. The purpose of this study was to investigate the effects of restoring diverse wetlands on wetland biodiversity and to understand the differences in communities and environmental factors between different types of the wetlands. Three different types (reed, temporary, and tidal) of wetlands were survayed, for fish, shrimp, crabs, birds, benthic invertebrates, water quality, sediment, and vegetation once every season from October 2016 to August 2017. The results showed that the environmental conditions differed among the different types of wetlands. The dissolved oxygen, pH and total phosphorus significantly differed in autumn and summer. During the whole year, the average salinity, the average water depth and sediment composition also significantly differed. The average water depth of the reed wetland was the highest, whereas the average salinity, water content of the substrate and organic matter of the tidal wetland was the highest. The main vegetation of the reed wetland was Phragmites australis, and the temporary wetland was Sporobolus virginicus, while the tidal wetland was Avicennia marina. There were species appeared only in specific type of wetlands. Biological community composition between the wetlands of different types differed.. In each seasons, the total number of species (total taxa) of all wetlands was higher than the number of species (total taxa) in any single type of wetlands, the beta diversity of wetlands was also higher among 3 types of wetlands. In summary showed, restoring diverse types of wetlands may increase the overall biodiversity of the overall.
