摘要
鸟类多样性是生物多样性的重要组成部分,监测鸟类多样性利于了解环境对生物的影响,及时施加正向干预,保护鸟类及其栖息环境。2016—2018年夏季采用样线法对秦岭西段麦积山区域的繁殖鸟类进行了调查,共记录到鸟类12目36科94种,种类最多的是雀形目(67种,占71.27%);国家Ⅱ级重点保护鸟类9种,CITES附录8种鸟类;鸟类区系组成中,古北界鸟类有13种(占13.83%),东洋界鸟类有23种(占24.47%),广布种有57种(占60.64%)。与其他生境相比,针阔叶混交林生境的鸟类物种最多(68种),常见种的种类也最多(29种),无优势种,环颈雉(Phasianus colchicus)在针叶林、灌丛、农田生境中均为优势种。生境生态位宽度值最大有5种鸟类:环颈雉1.004、红嘴蓝鹊(Urocissa erythroryncha)0.920、强脚树莺(Horornis fortipes)0.781、云南柳莺(Phylloscopus yunnanensis)0.775和橙翅噪鹛(Trochalopteron elliotii)0.720;聚类分析表明,在相似度为50%时,区域内常见鸟类可划分为5个伴生类群。
From 2016 to 2018,we studied breeding birds in the Maiji Mountain area of the western Qinling range in western China.We sampled line transects to identify and count birds.We recorded a total of 94 bird species representing 12 orders and 36 families.The largest number of species represented the order Passeriformes(67 species,71%).There were 9 species of class II national protected species,and 8 species of birds listed in CITES appendices.Among the bird fauna,13 species(14%)were Palearctic,23 species(24%)were of eastern Oceania,57 species(61%)were of wide distribution.Compared with other habitats,coniferous and broad-leaved mixed forest habitats had the largest number of bird species(68 species),the most common species(29 species),but no dominant species.Common pheasant(Phasianus colchicus)was the dominant species in coniferous forest,thicket,and farmland.The five species with the largest habitat niche width were common pheasant 1.004,red-billed blue magpie(Urocissa erythroryncha)0.920,brown-flanked bush warbler(Horornis fortipes)0.781,Chinese leaf warbler(Phylloscopus yunnanensis)0.775,and Elliot s laughingthrush(Trochalopteron elliotii)0.720.The cluster analysis results show that when similarity was 50%,the common birds in the region can be roughly divided into five associated groups.
