Analysis of bird community structure in Gande County,Qinghai Province
摘要
Abstract
To analyze the structural characteristics of the bird community in Gande County,Qinghai Province,a sys-tematic survey was conducted in four typical bird habitats in this county,namely grassland meadows,alpine shrubs,river wetlands,and alpine bare rocks,using the transect line method in January and July 2021.A total of 90 bird species of be-longing to 16 orders and 36 families were recorded by combining this survey with a review of Qinghai bird atlas.In terms of community composition,the number of Passeriformes birds was the largest,with a total of 49 species,accounting for 54.44%.There were 41 non-Passeriformes bird species,accounting for 45.56%.According to the zoogeographical re-gions,among the 90 bird species,widespread species had the highest proportion(66.67%),followed by Palearctic spe-cies(33.33%),and there were no species from the Oriental realm.In terms of residential types,resident birds had the highest proportion(51.11%),followed by summer migrants(33.33%),passage migrants accounted for 12.22%,and winter migrants had the smallest proportion(3.33%).The area is rich in rare species,with 6 species of national first-level protected wild animals and 14 species of national second-level protected wild animals.There are 2 species listed in Con-vention on International Trade in Endangered Species of Wild Fauna and Flora(CITES)Appendix Ⅰ and 6 species listed in Appendix Ⅱ.There are 2 species listed as endangered in International Union for Conservation of Nature(IUCN)Red List,3 species listed as near threatened,and 6 species endemic to China.Comparing the bird species in different habitats,the grassland meadow habitat had the highest number of bird species(34 species),while the alpine bare rock habitat had the lowest number of bird species(4 species).Analysis of community species diversity showed that the alpine scrub habitat had the highest species diversity index(2.35),while the alpine bare rock habitat had the lowest diversity index(0.79).The vertical distribution of bird diversity showed a mid-peak pattern.This study reveals the current status of bird commu-nity structure in Gande County and provides important data for local bird conservation and ecological studies.关键词
