摘　　要：近年来,随着城市化的发展,野生动物栖息地的减少,使得城市中动物的种类和数量也急剧下降。山斑鸠作为城市鸟类动物多样性的重要组成部分,其栖息环境更需严格保护。通过拉萨市区的6个具有代表性地点对山斑鸠的栖息地选择进行了初步调查研究;用主成分分析(PCA)6个栖息地,最终得到6个地区的主成分综合得分排序表,山斑鸠对栖息地环境的选择更倾向于宗角禄康处;采用广义线性模型分析物种数量与栖息物的相关性,结果表明山斑鸠与藏川杨(β=0.022028,SE=0.002418,p<0.0001)、垂柳(β=0.016775,SE=0.006063,p=0.00566)、房屋(β=0.022242,SE=0.002282,p<0.0001)、草坪(β=0.01663,SE=0.005041,p=0.000971)、电线杆(β=0.065375,SE=0.007885,p<0.0001)、路灯(β=0.03329,SE=0.006491,p<0.0001)和路沿(β=0.028988,SE=0.007119,p<0.0001)等栖息物有显著正相关;通过卡方检验(Chi-square Test)分析物种数量与栖息物的差异,结果发现山斑鸠的数量与14个栖息物之间有显著差异,并构建模型,通过AIC准则选出最优模型。In recent years, with the increase of urbanization, the habitat of wild animals is reduced, making the species and number of animals in the city also sharply decreased.Turtledove is an important part of the diversity of urban birds and animals, and its habitat is indispensable.In this paper, the habitat selection of mountain turtledove was investigated in 6 representative sites in Lhasa.Principal component analysis(PCA) was used to analyze 6 habitats, and the principal component comprehensive score ranking table of 6 regions was finally obtained.The choice of habitat environment for mountain turtle doves was more inclined to live in jiaolukang.A generalized linear model was used to analyze the correlation between the number of species and the habitats.The results showed that the relationship between the number of species and populus Tibetan(β=0.022 028,SE=0.002 418,p<0.000 1,weeping willow(β=0.016 775,SE=0.006 063,p=0.005 66),house(β=0.022 242,SE=0.002 282,p<0.000 1),lawn(β=0.016 63,SE=0.005 041,p=0.000 971),telephone pole(β=0.065 375,SE=0.007 885,p<0.000 1),street light(β=0.033 29,SE=0.006 491,p<0.000 1) and roadside(β=0.028 988,SE=0.007 119,p<0.000 1) and other habitats had significant positive correlation;Chi-square Test was used to analyze the difference between the number of species and the habitats.The results showed that there was a significant difference between the number of mountain turtle doves and the 14 habitats.The model was built and the optimal model was selected by AIC criterion.
