弥渡县鸟类多样性研究

Study on Bird Diversity in Midu County

2019年1月采用样线法和样点法对云南省大理白族自治州弥渡县进行了鸟类资源本底调查,并查阅了相关文献.结果共记录弥渡县鸟类14目34科160种,其中雀形目鸟类108种,非雀形目52种,包括国家一级保护鸟类1种,国家二级保护鸟类9种.居留类型分析显示,共有留鸟82种,冬候鸟32种,夏候鸟20种,繁殖鸟16种,旅鸟10种.区系划分以东洋种占优势:东洋种78种(48.75%),古北种36种(22.5%),广布种46种(28.75%).弥渡县鸟类的属间多样性指数(D G)为10.683,科间多样性指数(D F)为18.437,G-F指数为0.421.D G<D F,D G/D F<1,表明科间多样性指数较高,而属间多样性较低;G-F指数偏低,说明单种科较多.

In January 2019,the birds in Midu County,Dali Prefecture,Yunnan Province were surveyed with the line transect method and the point count method.A total of 160 bird species were recorded,belonging to 34 families and 14 orders.Among them,108 species were passerines and 52 species were non-passerines.There were 1 national first class protected species and 9 national second class protected species.The fauna was dominated by the Oriental species at 48.75%.The G index of birds of Midu County was 10.683,and the F index was 18.437,and G-F index was 0.421.Since D G<D F,it is indicated that the inter-family diversity index was high and the inter-genus diversity was low.Meanwhile,the low G-F index indicates that single-species families were abundant.
