摘要
1995~ 1997年的两个冬季 ,在黑龙江省东京城林业局对原麝和斑羚的食物组成、采食高度和栖息地进行了调查研究 ,旨在探讨两种动物的冬季种间关系。原麝冬季的主要食物是松萝、杨、桦、榛、柳、苔藓类和地衣类 ,斑羚冬季的主要食物是枯落叶、蒙古柞、苔草、老鹳草、杨和问荆。两种动物采食高度的分布均为正态分布 ,原麝采食高度集中在 6 0~ 12 0 cm,斑羚采食高度集中在 30~ 80 cm。原麝和斑羚对针阔混交林的利用程度均表现为最高水平。原麝与斑羚在食物、采食高度和栖息地 3个生态位维上均有 50 %以上的重叠 。
The food habitat, foraging heights and habitats of Musk deer and Goral were investigated in winter from 1995 to 1997 in Dongjingcheng forest region. The goal is to probe into the inter-specific relationships of two species in winter. The staple foods of musk deer were Usnea spp, Populus spp., Betula spp., Corylus spp., Salix spp.,Bryophytes and Lichen. Those of groal were leaf litter , Quercus mongolica ,Carex spp., Geranium spp., Populus spp. and Equisetum spp.. Statistically the foraging heights of two species were normally distributed. Musk deer foraging height was 60~120cm; goral foraging height was 30~80cm. Two species mostly use mixed coniferous and broad-leaf forests. Two species in food, foraging height and habitat niche dimension are the great overlap, but habitat niche dimension overlap is highest.
