摘　　要：【目的】为了更好地保护藏乌鸫(Turdus merula maximus),对西藏拉萨市区的藏乌鸫栖息地进行调查。【方法】对调查数据进行主成分分析,并以AIC准则为基础筛选模型,对最优模型进行多元线性回归检验,从而确定藏乌鸫栖息地选择模型。【结果】藏乌鸫栖息地选择的回归模型为:总数=0.372+0.912*杨树+1.086*柳树+1.067*草本(P<0.001,R^(2)=0.977)。【结论】草地具有为藏乌鸫提供食物和生存空间等功能,是拉萨市藏乌鸫主要的栖息场所。【Objective】In order to better protect Turdus merula maximus,its habitat in Lhasa urban section was investigated.【Method】The data obtained from the survey were subjected to principal compo-nent analysis,and the model was screened based on the AIC criterion,and then the optimal model was tested by a multiple linear regression to ascertain the habitat selection model of T.merula maximus.【Re-sult】T.merula maximuss habitat preference was predicted by the following regression equation:total=0.372+0.912∗poplar+1.086∗willow+1.067∗grassland(P<0.001,R^(2)=0.977).【Conclusion】T.merula maximuss primary habitat in Lhasa is grassland,which serves as a source of food,shelter,and other needs.
