Investigation and diversity study of waterbird in luanhekou wetland

The Luanhekou wetland serves as a crucial breeding and migratory stopover site for waterbirds along the East Asian-Australasian flyway, In order to determine the current status of the waterbirds in the wetlands, the diversity of the waterbirds is surveyed by line transects and point count methods from 2022 to 2024. The results indicated the presence of 73 species of waterbirds belonging to 14 families and 6 orders, The majority of these waterbirds belong to the Charadriiformes order and are primarily waders in terms of ecological groups. The analysis of residence patterns revealed that they are predominantly migratory birds. The avifauna is predominantly composed of Palearctic species, with 14 species being nationally protected. Compared to 2023, the diversity index and Pielou index of waterbird community that stopped over at the Luanhekou wetland in 2024 showed an increase, with a higher level of diversity in the autumn bird community throughout the year. The results of this study can provide a scientific basis for the ecological restoration initiatives and sustainable development of the Luanhekou wetland.
