Abstract: Winter food-habits cf red deer (Cereus elaphus)was studied with the microhisto-
logical analysis technique of feces in combination with field browse Surveys from 1985：0 1987 in Dailing Region Results showed that populus spp．， Betula Spp．，Salix spp．，and Tilia amuremsis were staples．The percentages of these items in diet were46.9% ，19.1% ，9.7% and 8.3% respectively．Red deer had positive selectivities for Acer tegmentosum ，Salix spp． and populus spp．，and negative selectivities for Betula Spp．， Tiliaa murensis，Aralia mandshurica and Sambucus coreana． They were arranged in order of preference as follows： Acer tegmentosum >Salix spp．> populus spp．>Sambucus coreana > Aralia mandshurica> Tilia amurensis>Betula spp．．A negative inttrrelationship existed between the content of hemicellolse and winter food preferences．Protein was sufficient for red deer， but energy might be a more critical facter to wintering red deer．

Key words: Red deer, food habits, selectivity, nutritional quality.

摘要： 1985-1987年在黑龙江省带岭林区，使用粪便显微组织学分析技术井结合野外啃食调查，对马魔冬季食性进行了研究。结果表明，杨，桦，柳，紫椴是其主要的冬季食物(46.9% ,19.1% ， 9.7%、 8.3% )。马鹿对杨、柳、青楷槭有正选择性，对桦、紫椴、刺老芽、接骨木有负选择性．马鹿对它们选择性的强弱顺序为：青槽槭>柳>杨>接骨木>刺者芽>紫椴>桦。被啃食植物中半纤维素的含量和马鹿对它们的选择性之间存在着一定的负相关关系。冬季马鹿并不缺乏蛋白质，而能量对越冬的马鹿可能是一个较为关键的因子。
