新疆托木尔峰国家级自然保护区北山羊分布调查
Distribution of the Ibex (Capra ibex) in Tomur National Nature Reserve of Xinjiang, China

摘要: 北山羊作为国家I级保护动物，目前对其研究仍然较少。2004年10—11月、2005年7月以及2005年10—12月三次对新疆托木尔峰国家级自然保护区北山羊（Capra ibex）的分布进行调查。通过定点搜寻、样线调查以及访问调查，其结果显示北山羊在保护区5个主要区域中的3个有分布，这3个区域是：琼台兰河谷地区、克其克台兰河谷地区、木扎特河谷地区；在托木尔河谷和库孜巴依河谷两个区域中，定点搜寻和样线调查均没有发现北山羊分布，但访问调查该区域有北山羊。通过此次调查得出托木尔峰自然保护区的大部分地区是北山羊分布区，说明该保护区在北山羊保护中的确起了重要作用，但北山羊在保护区中的不均匀分布现状值得注意，这种现象可能与人为活动干扰有关。Abstract: Ibex (Capra ibex), a first grade protected animal, has not been well studied in China. Surveys were conducted to investigate the distribution of the ibex in the Tomur National Nature Reserve during October－November 2004, July 2005, and October―December 2005. The results were as follows：① Out of five valleys, the ibex was distributed in the Qiong-Tailan, Keqik-Tailan, and Muzart Valleys；② Ibexes were not observed in the Tomur Valley and Kuzbayi Valley in our surveys, but interview investigations indicated that they may be found here as well. Our results indicated that the nature reserve as a whole is in the distribution range of ibex and it plays an important role in protecting ibex and the alpine biodiversity. However, the uneven distribution pattern can be due to human activities. Therefore, the management of the reserve needs to be improved in the future.
