摘　　要：西双版纳的林下层鸟类以多物种、低密度为特征,而华南地区普遍以灰眶雀鹛单优势种为特征。为了探究云南其他地区林下层鸟类群落的特点是否类似于西双版纳以及云南的地形地势对林下层鸟类的影响,于2011年11月—2012年9月,采用雾网法研究了位于红河断裂带以东的滇东南大围山、滇西北鸡足山常绿阔叶林的林下鸟类群落。大围山张网5614网·h,捕获林下鸟类52种735只,隶属于13科3目;鸡足山共张网4731网·h,捕获林下鸟类45种413只,隶属于15科2目。大围山和鸡足山林下鸟类物种多样性低于西双版纳勐养林下鸟类物种多样性,大围山和鸡足山优势鸟种占的比例高于勐养优势种的比例、尤其是灰眶雀鹛占的比例高,大围山和鸡足山两地的留鸟物种组成相似性高、而与勐养相差较远,大围山和鸡足山两地的候鸟的比例也高于西双版纳勐养地区候鸟的比例。本文分析了大围山、鸡足山和勐养的自然地理格局及其林下鸟类群落组成特点,认为云南红河断裂带对林下鸟类群落组成有明显影响。The understory birds in Xishuangbanna, Yunnan is characterized of higher species richness and lower species density compared to South China, where the Greycheeked Fulvetta （Alcippe morrisonia） is the most dominant species. To explore whether characteristics of understory birds in other areas of Yunnan are the same as in Xishuangbanna, and assess how topography impacts the understory bird community, we sampled birds in the evergreen broadleaved forests of Daweishan, southeast Yunnan and Jizushan, northwest Yunnan using mist nets from November 2011 to September 2012. The two sites are on the east of Red River Fault Zone. A total of 735 individuals from 52 species, 13 families and 3 orders were captured within 5614 net hours at Daweishan, and a total of 413 individuals from 45 species, 15 families and 2 orders were captured within 4731 net hours at Jizushan. Our results showed that species diversities of Daweishan and Jizushan communities were lower than that of monsoon evergreen broadleaved forest of Mengyang, Xishuangbanna; dominant species, especially the grey-cheeked fulvetta, accounted for a higher proportion in Daweishan and Jizushan than in Mengyang; as regard to resident species, Daweishan and Jizushan communities had high similarity but were quite different from Mengyang community; more migratory individuals were caught in Daweishan and Jizushan communities than in Mengyang community. We concluded that Red River Fault Zone had a significant impact on the understory bird community compositions by a comprehensive analysis of natural geography of Daweishan, Jizushan and Mengyang, as well as their bird community compositions.
