摘要
将川西高原黑熊划分4个年龄组。发现黑熊幼体的尺骨与桡骨交叉扭曲程度大于成体,并随年龄增长逐渐趋于平行。获得黑熊食性及越冬信息。川西高原黑熊应归属为黑熊的指名亚种。
We distinguished black bears into four age classes. We made a careful comparison and found that the ulnae of young black bears was more curved toward their radiuses. Ulnae and radiues became parallel gradully as the age incteasing. Some information about the black bears food habits and hibernation was acquired. We classfied the black bears in west Sichuan plateau as Setenarcto thibetanus tbibetanus.
