摘要
2013-2015年冬季,在黑龙江省大兴安岭新林林区对紫貂(Martes zibellina)的生境选择进行了野外调查研究.通过大兴安岭紫貂冬季对海拔、坡度、坡向、距水源距离、距道路距离、距针叶林距离、距阔叶林距离、距混交林距离、距灌木距离、距沼泽距离、距居民点距离、隐蔽级、郁闭度、雪深、植被类型、优势乔木共16种生境因子的选择研究,发现新林林区冬季紫貂更偏爱海拔较高、距离水源较近、距离道路和居民点较远、距离混交林较近、郁闭度更高的生境.通过对生境因子进行逻辑斯蒂回归筛选,建立了紫貂生境选择的资源选择函数模型,该模型的选取变量也支持了海拔、距道路距离、距水源距离的差异.这表明该林区紫貂偏爱海拔较高的生境,活动在水源较近的区域,回避人为干扰,选择郁闭度较高的生境.
Abstract
The field investigation was conducted on habitat selection of Martes zibellinain Xinlin,Greater Khingan Mountains,Heilongjiang Province.Through study on selection of 16 kinds of habitat factors,including elevation,slope degree,slope direction,distance to water source,distance to road,distance to coniferous,distance to broad-leaf,distance to mixed,distance to shrub,distance to swamp,distance to residents,hiding cover,canopy closure,snow depth,vegetation types,dominant tree,it was found that Martes zibellinain Xinlin forest area in winter prefer to higher elevation and canopy closure,near water source and mixed forest,far from road and residential sites.By Logistic regression screening of habitat factors,resource selection function model was established.Selected variables of resource selection function model also supported the difference of elevation,distance to road,distance to water source.It was indicated that Martes zibellinain Xinlin forest area preferred high altitude,high canopy density,near water,avoiding human disturbance.
