中文摘要:

马鹿塔里木亚种分布于新疆塔里木盆地各沿河地带,强度适应荒漠生境。采用分子系统学方法研究表明,世界马鹿分为东西两大系统,马鹿塔里木亚种是我国唯一属于西部系统的亚种。在中国濒危动物红皮书中被列为濒危(E)亚种,按国际自然与自然资源保护联盟(IUCN)1993年制定的世界物种红色名录濒危定级标准,属于极危级(EN)。自20世纪50年代以来,由于自然和人为因素的影响,种群数量急骤下降,现今马鹿塔里木亚种在塔河流域被隔离为莎雅、尉犁和且末3个小种群,当前该亚种正受到栖息地减小和片断化的双重影响,而且因遗传漂变和近亲繁殖的不断增加也进一步加剧它的濒危程度。为有效保护该物种特提出可行的保护建议。

英文摘要:

The Tarim red deer inhabits in the river valley of the Tarim, Konqi and Qarqan rivers in Xinjiang, China. Since 1950, due to the affections of nature and human, the population of ths subspecies has been urgently declined and the Tarim red deer has been included in the Red List of the International Union for the Conservation of Nature and Natural Resources (IUCN) in the category of an endangered species and classified as a second class protected animal in China. Currently, the habitat of the Tarim red deer is an area of intensive human activities, therefore the deer population isolated into three areas, namely Xayar, Lopnur and Qarqan. Even more with the habitat's decreasing, not only the subspecies lost it's genetic diversity but also the animals are in severe danger because of genetic drifting and close relative reproduction. So far, the protective measure that has been not been sufficiently effective, and the ecology and genetic features of this subspecies remain to be elucidated. For that, some effective measures must be taken at present and its nature reserve must be set up irnmediantely.
