摘　　要：本文介绍了资源选择函数的原理与方法,并应用在丹顶鹤对巢址生境的选择和利用研究中。研究影响丹顶鹤巢址生境选择的关键因子是人为干扰距离;次关键因子是植被密度、植被高度、明水面距离及植被直径;而剩余苇丛距离、剩余苇丛面积、剩余苇丛高度和巢周围水深对丹顶鹤巢址生境选择的影响并不明显。丹顶鹤的生境资源选择函数为:Logit(p)=-2.409+4.226×植被高度+1.835×植被直径+2.416×植被密度-5.023×人为干扰距离+2.009×明水面距离。本文还探讨了资源选择函数的理论基础和该模型在丹顶鹤巢址生境中失拟的原因,同时与主成分分析法的结果进行了比较,结果表明资源选择函数在研究动物的生境偏好方面有明显优势。We introduce the theory and methodology of resource selection functions and resource selection Index and use these methods to analyze nest site selection by red-crowned crane(Grus japonensis).Human disturbance distance was the key factor influencing habitat selection.The secondary key factors were vegetation density,vegetation height,distance to open water,and vegetation diameter.Random factors were distance,area,and height of remnant reed cluster and water depth around nests.The resource selection function(RSF)yielded a log-linear model:Logit(p)=-2.409+4.226×vegetation height+1.835×vegetation diameter+2.416×vegetation density-5.023×human disturbance+2.009×distance to open water.We discuss the theoretical basis and reason for failure in generating an RSF mode.Comparison between the results of RSF and principal component analysis revealed the superiority of RSF in study of habitat preference of wildlife.
