The area was divided into plot A and plot B, which included nest patches and control patches. Taking nest as center, the environmental factors of nest plot (1 m×1 m) and control plot were recorded and compared. The results showed that the height of the tallest plant and their distance to the bank in nest plot were significant higher than those in control plot. Principal component analysis on 14 habitat factors showed that T. ruficollis preferred to nest in small patches with high, sparse and few low stem plants. More nests presented in the area with abundant food. These results had practical significance on the conservation of T. ruficollis, and also provided basic information for the study of avian nest site selection in alpine wetland ecosystem. 2017,36(2): 174-180 收稿日期：2016-08-28 DOI：10.11984/j.issn.1000-7083.20160230 分类号：Q958.1;Q959.7 基金项目：贵州省科技厅、黔东南州科技局、凯里学院科技合作协议项目（黔科合LH字[2015]7755号）；贵州省高校优秀科技创新人才支持计划项目（黔教合KY字[2014]252号）；凯里学院校级重点课题项目（Z1301）；贵州省教育厅优秀科研创新团队项目"黔东南生物多样性保护和利用创新团队"项目（黔教合人才团队字[2013]26） 作者简介：罗祖奎(1974-),男,博士,副教授,研究方向:鸟类生态学,E-mail:luozukui@126.com 参考文献： 李文静, 王剑伟, 谢从新, 等. 2007. 厚颌鲂(Megalobrama pellegrini)的繁殖生物学特征[J]. 生态学报, 27(5):1917-1925. 刘学昌, 吴庆明, 邹红菲, 等. 2009. 丹顶鹤(Grus japonensis)东、西种群巢址选择的分异[J]. 生态学报, 29(8):4483-4491. 罗祖奎, 刘伦沛, 李东平, 等. 2013. 上海大莲湖春季鲫鱼生境选择[J]. 宁夏大学学报(自然科学版), 34(1):70-74. 约翰·马敬能, 卡伦·菲利普斯, 何芬奇. 2000. 中国野外鸟类手册[M]. 长沙:湖南教育出版社. 张华海, 李明晶, 姚松林. 2007. 草海研究[M]. 贵阳:贵州科技出版社. 周立晨, 罗祖奎, 牛俊英, 等. 2013. 贵州省越冬区斑头雁种群动态与生境选择[J]. 东北林业大学学报, 41(3):122-126.
