摘　　要：2003年8～9月,对青海省境内普氏原羚的分布和种群数量进行了专项调查。调查结果表明,普氏原羚现存7个种群,累计数量为602只;其中塔勒旋果种群属首次报道。与以往报道相比,目前元者和鸟岛种群数量呈下降趋势;海晏—刚察种群数量增长明显;湖东—克图种群数量有所回升,但仍没有达到20世纪80年代中期时的种群数量。普氏原羚种群数量变化与栖息地质量及人为干扰程度有密切相关。本次调查显示,普氏原羚现存栖息地呈不连续的间断分布,随着区域经济开发力度的加大,其栖息地在不断缩减、生存环境质量仍在继续恶化。There were 4 populations and less than 350 individuals of the Przewalski＇ s gazelle （ Procapra przewalskii ） , an endemic and critically endangered species, in Qinghai Province. In order to provide accurate information about this species, the distribution and population size of Przewalski＇ s gazelle in Qinghai Province, were specially investigated from August to September, 2003, The results of this investigation showed that there are 7 isolated populations and 602 individuals of Przewalski＇ s gazelle in Qinghai Province presently. These populations include Yuanzhe population, Hudong-Ketu population, Haiyan-Gangcha population, Talixuanguo population, Bird-island population, Shengge population and Qiejitan population. The Talixuanguo population was reported for the first time, Comparing our results with those of the earlier report shows： （1） the population counts in Yuanzhe and Bird-island show declining tendencies; （2） the count for the HaiyanGangcha population obviously increased; and （3） the Hudong-Ketu population size appears to be increasing. These changes are related to the quality of animal habitat and the degree of artificial disturbance. These results were demonstrate： （ 1 ） the extant popldations of Przewalski＇ s gazelle show evidently patchy distribution, （ 2 ） the hahitat of this animal is descreasing, （3） the habitat quality of the gazelle is still deteriorating. Accompanying economic development of this species＇ distribution area, protection will be very important.
