Abstract
了解鸟类资源状况、群落结构和空间分布特征是后续开展长期鸟类监测的工作基础.通过样线和网捕环志调查并综合之前的访问调查记录,在唐家河国家级自然保护区共发现鸟类313种,分属于16目57科.从居留型看,留鸟182种,候鸟109种(其中夏候鸟90种、冬候鸟19种),旅鸟及迷鸟22种.国家一级保护鸟类6种,二级保护鸟类42种.鸟类分布型共有13种,以东洋型(76种鸟)和喜马拉雅—横断山区型(68种鸟)为主.各类生境中的鸟类多样性由高到低依次为常绿阔叶林,常绿与落叶阔叶混交林,针阔混交林,农田,亚高山针叶林,高山灌丛与高山草甸.总体上,唐家河保护区鸟类特有种和受保护物种较多,群落结构与生境关系密切,生物多样性随着海拔的上升而缓慢下降
