摘 要 ：研究表明,蒙新河狸(Castor fiber birulai Serebrennikov)采食植物达49种其中木本植物15种。常采食植物仅为几种,柳树为其关键食物。夏季蒙新河狸以柳树萌生枝条为主要食物,一般不啃伐大的林木:秋季大量啃伐林大营建食物堆以为冬季贮食,贮食期约持续1个月,每个家族在冰下贮存1000—2000kg的杨柳枝条。全年以秋季进食量最大,约为冬季的2倍。

Abstract:Beaver‘s diet in Xinjiang contains about 49 species of plants including 15species of woody plants. The key foods of beavers are willows. Beavers mainly feed willow sprigs in summer. In fall, beavers forage a large number of trees to make a food cache weighing about 1000~2000kg for winter use. The foraging period lasts about one month. Food intake in fall is the largest of a year, which is about two times larger than in winter.
