摘要: 北山羊(Capra sibirica)是一种主要分布于中亚高山地带的有蹄类物种,中国国家I级重点保护野生动物。北山羊选择陡峭悬崖作为栖息地,采食集中于禾本科和莎草科植物。北山羊具有典型的雌雄异形现象,雄性体型大于雌性。除交配期外,成年雌雄个体之间同性集群现象明显。近年来,由于偷猎、栖息地丧失和疾病等原因的影响,北山羊种群数量不断减少。为保护此物种,国内外学者针对北山羊开展了大量研究。本文从种属划分、形态与生理、种群密度和数量、生境选择、时间分配与活动节律、集群、濒危原因与保护对策等方面对北山羊的研究现状进行了综述,分析亟待深入研究的内容,北山羊同性集群及食性研究应是下一步工作重点。

Abstract: Capra sibirica is an important alpine ungulate species in high mountain regions of Central Asia, and ranks in grade I key protected wildlife in China. C. sibirica generally prefers rocky habitat and a considerable portion of their diet is comprised of Gramineae and Cyperaceae. C. sibirica is a sexual dimorphism ungulate species in morphology; males are much larger than females. Mature male and female ibexes live in separate groups except in the breeding season. The population amount of C. sibirica has decreased sharply since recent decades due to overhunting and poaching, habitat loss and disease. Researchers around the world have carried out a number of studies in order to protect this species. The present paper summarized the main results of these studies from the aspects of species classification, morphology and physiology, population density and quantity, habitat selection, time budget and activity rhythm, gregarious behavior, the endangered cause and protection strategy. The future study should focus on the sexual segregation and food habits of C. sibirica.
