Spatiotemporal diversity of waterbirds in Jiaozuo section of Yellow River wetland
In order to understand the species composition and spatiotemporal diversity of waterbirds in the Jiaozuo section of the Yellow River wetland,waterbird investigations were conducted in Mengzhou,Wen and Wuzhi Counties of the Jiaozuo section of the Yellow River wetland using the line transect method in summer(June 2022),autumn(Septem-ber 2022),winter(December 2022)and spring(March 2023)in this study.The species and numbers of waterbirds were counted,and the spatiotemporal diversity was analyzed using the iNEXT package of R software.A total of 4 853 water-birds were observed in 4 surveys,belonging to 44 species of 9 orders,14 families.In summer,863 waterbirds from 17 species,11 families,and 7 orders were observed;in autumn,578 waterbirds of 19 species,9 families and 7 orders were observed;in winter,1 161 waterbirds of 24 species,10 families and 7 orders were observed;in spring,2 251 waterbirds of 19 species,7 families and 7 orders were observed.In Mengzhou,4 236 waterbirds of 39 species of 8 orders,13 fami-lies were observed;in Wen County,511 waterbirds of 26 species of 8 orders,11 families were observed;in Wuzhi Coun-ty,106 waterbirds of 17 species of 6 orders,8 families were observed.The spatiotemporal diversity study showed that the species richness of the Jiaozuo section of the Yellow River wetland was the highest in winter and in Mengzhou.Meng-zhou had a better ecological environment and more waterbird species and individuals,while the effective numbers of domi-nant species and common species of waterbirds in Wen County and Wuzhi County were higher.The results of this study have important reference value for wetland protection in the Jiaozuo section of the Yellow River basin.
