普氏原羚分布、种群和保护现状

普氏原羚(Procapra przewalskii)是青藏高原特有物种, 为了掌握该物种的分布和种群状况, 我们于2014-2015年采用全面调查和直接计数的方法, 对普氏原羚的分布、种群和保护现状进行了调查。结果如下: 普氏原羚分布在青海湖周边12个隔离的分布点, 与全国第一次野生动物资源调查的结果相比, 有多个新的分布点被发现, 分布范围和面积扩大; 调查共发现1,238只普氏原羚, 与2010年以后的调查结果相比, 种群数量维持在一个稳定的水平。然而, 仅有4个分布点位于青海湖国家级自然保护区范围内。尽管刚察县成立了青海湖普氏原羚特护区, 天峻县成立了普氏原羚自然保护站, 但现有的管护力度仍然不够, 且缺乏系统的管理规划。我们建议在天峻县布哈河上游的生格-快尔玛地区成立普氏原羚自然保护区; 同时建立适当的生态补偿机制, 协调保护与社区发展的矛盾; 鉴于目前圈养种群发展迅速, 建议在历史分布区选取合适的地点进行人工繁育个体的迁地放归。

The distribution,population and conservation status of Przewalski’s gazelle,Procapra przewalskii

We conducted surveys on the distribution, population, and conservation status of Przewalski’s gazelle, Procapra przewalskii, using the total count method in 2014 and 2015. Przewalski’s gazelle was found in 12 separate locations around Qinghai Lake. Compared with results from the First National Wildlife Survey, several new locations were found, and both the distribution range and area were enlarged. At least 1,238 individuals were found around Qinghai Lake. Compared with survey results collected after 2010, the population size of Przewalski’s gazelle reached a relatively stable level. Although four locations of Przewalski’s gazelle were under the protection of the Qinghai Lake National Nature Reserve, and special conservation areas and protection stations for the gazelle were also established, overall conservation efforts are still insufficient. A nature reserve that is specifically focused on the conservation of Przewalski’s gazelle should be established in the Upper Buha River of the Shengge-Kuaierma region in Tianjun County. Moreover, proper ecological compensation mechanisms should be developed to resolve the contradiction between conservation and economic development. Considering the fast growth of the captive-bred population, future reintroductions should be conducted in suitable locations within the historical range of this gazelle outside the Qinghai Lake basin.
