Zusammenfassung: | The Three-River-Source National Park located at the hinterland of Qinghai-Tibet Plateau, is the most concentrated biodiversity hotspot. From 2015 to 2017, the faunas and the distribution of wide birds in the Three-River-Source National Park were surveyed. Based on the results of field surveys and previously reported data, 196 bird species were recorded in the national park, belonging to 18 orders, 45 families, and 121 genera. In total 59 species of protected birds are present in the park, exceeding the total number of distributed birds by 30.1%. There are 8 and 27 species among class I and II nationwide key protected birds, respectively, and 24 species were enlisted as key protected animals of Qinghai Province. In addition, there are 120 species of birds in the list of beneficial species. Furthermore, 39 species were classified under the threatened(including endangered, vulnerable and near danger) category in the Red List of China′s Vertebrates, accounting for 19.9% species distributed in the Three-River-Source National Park. Fifteen species were endemic to China, accounting for 7.65%. In terms of geographical distribution, the Three-River-Source National Park is located in the Qinghai-Tibet region of the ancient northern boundary, with 145 species of the ancient northern boundary, 37 species of the eastern ocean boundary, and 14 widely distributed species. The results of G-F index analysis revealed that species diversity was high in the Three-River-Source National Park. Comparison of the average faunal similarity between the Chang Jiang River Source park, the Lan Cang River Source Park, and the Yellow River Source Park revealed that the three zones are all closely related. Bird species in the Three-River-Source National Park display high biodiversity, being rich in endemic, rare, and endangered species, with a very high significance and value for protection. |
