摘 要：
2007和2008年11—12月在黑龙江省完达山东部林区的五泡林场和河口林场对狍子冬季生境选择进行了研究。通过在野外布设110条样线,每条样线长5km,样线间间距2km的方法收集生境数据,利用资源选择指数(RSI)和资源选择函数(RSF)分析狍子冬季生境选择。结果表明:狍子偏向于选择针阔混交林(资源选择指数Si=0.37)和阔叶林(Si=0.19)、隐蔽度在35%～70%(Si=0.46)、郁闭度在35%～70%(Si=0.61)、盖度为10%～20%(Si=0.27)、坡度<25°(Si=0.18)、乔木密度>0.06株/m2(Si=0.59)、乔木胸径<15cm(Si=0.66)、人为干扰距离>500m(Si=0.12,Si=0.30)、中坡位(Si=0.14)、阳坡(Si=0.44)的生境;狍子对灌丛(Si=-0.05)、郁闭度<35%(Si=-0.03)、盖度<10%(Si=0.04)的生境表现出随机选择;不喜欢选择针叶混交林(Si=-0.56),不选择农田生境(Si=-1.00)。狍子在完达山东部林区的生境资源选择函数为logit(P)=-11.17+0.71×隐蔽度+3.24×坡向+0.59×食物丰富度-0.62×干扰距离-0.25×乔木胸径+0.01×灌木密度+0.07×坡位,狍子对生境的选择概率为P=elogit(P)/(1+elogit(P))。

摘 要：
Based on field data collected by transect lines,winter habitat selection by roe deer(Capreolus capreolus) was studied using a Resource Selection Index(RSI) and Resource Selection Functions(RSF) in the eastern Wandashan mountains,Heilongjiang Province during the winters from November to December of 2007 and 2008.We set 110 systematic transect lines with interval distances of 2 km,each 5 km in length.The following location characteristics were collected at active locations of roe deer and control locations:habitat type,food abundance,slope,slope position,aspect,elevation,shelter class,canopy,degree of coverage,tree density,diameter at breast height(DBH),shrub density and distance to human disturbance.The results showed that roe deer preferred mixed coniferous-broadleaf forests(Si=0.37),mixed broad-leaf forests(Si=0.19),moderate shelter class(35%-70%)(Si=0.46),moderate canopy degree(35%-70%)(Si=0.61),moderate coverage degree(10%-20%)(Si=0.27),slope(<25°)(Si=0.18),sunny aspect(Si=0.44),middle slope position(Si=0.14),large numbers of tree(>0.06 trees /m2)(Si=0.59),lower diameter of tree(<15 cm)(Si=0.66) and more distance to human disturbance(>500m)(Si=0.12,Si=0.30).The roe deer avoided
