摘要
分布于新疆境内的欧亚河狸为 2 0 0万年前的孑遗种群 ,具有极为独特的生物学特性 ,其皮毛和香腺分泌物———河狸香极为珍贵 ;同时由于其生存环境日益受到人类活动的威胁 ,河狸的生存空间越来越小 ,因此 ,保护与开发利用河狸资源具有极为重要的现实意义和历史意义。
Castor fiber that distributes in Xinjiang is the epibiotic species population that have extremely distinct bionomics,and the fur and the frangrant from it's glandule are very rare.Meanwhile ,living space of castor fiber has become smaller and smaller because of the activity of mankind , therefore the protection and exploitation of the resources of castor fiber have important realistic and historical significance.
