摘要
2013年1月17日至2月8日,在龙马山对黑白仰鼻猴夜宿地的选择利用情况进行调查研究,共调查20个夜宿地样方和20个非夜宿地对照样方,并对夜宿地13个生态因子进行主成分分析;用非参数估计中的秩和检验对夜宿地与非夜宿地的13个生态因子进行比较分析。结果表明:龙马山黑白仰鼻猴的夜宿地选择主要受乔木高度和松萝分布的影响,同时还受到乔木冠幅、乔木胸径、海拔和人为干扰等其他生态因子的影响。
We made a study on the ecological factors which have an important relationship with the sleeping sites ofRhinopithecus bieti in Longma Mountain from January 17th to February 8th in 2013.It includes a comparison between the formal sleeping sites （N =20） and informal sleeping sites （N =20） in all.The principal components analysis focuses on 13 ecological factors in formal sleeping sites.We also made a study on Mann-Whitey U.The study showed that the selection of Rhinopithecus bieti＇s sleeping sites has a very close relationship with the tree height and the distribution of usnea,as well as the tree crown,the average DBH of trees,the elevation,the human disturbance and other ecological factors.
