索加-曲麻河保护分区野生陆栖脊椎动物分布型研究

Research on Distribution Patterns of Wild Terrestrial Vertebrates in Suojia-Qumahe Nature Reserve's Subarea

采用实地调查、访谈和查阅文献的研究方法,得出了索加-曲麻河保护分区共有131种野生陆栖脊椎动物,含国家级重点保护动物26种,占三江源自然保护区国家级保护物种总数的37.68%,因此具有重要的保护意义。同时对该保护分区内物种进行了分布型分析,结果表明:从世界动物地理分区特征分析,物种组成以古北界成分居多,占总数的80.15%,东洋界成分仅占19.85%;从中国陆栖脊椎动物分布型角度分析,共计11个分布型,其中高地型动物种类最多并占所有种数的32.06%。

Adopting the research methods of field investigation ,interview and literature review ,the article finds that there are 131 species of wild terrestrial vertebrates in Suojia - Qumahe Nature Reserve＆#39;s subarea ,including 26 nationwide protected species which account for 37 .68% of total nationwide protected species in the Sanjiangyuan Nature Reserve .Therefore ,the protection of Suojia-Qumahe Nature Reserve＇s subarea is of great importance .In the meantime ,the article conducts a analysis about distribution patterns of the species in Suojia -Qumahe Nature Reserve＇s subarea and ,the results are as follow ：from the aspect of world geographical distribution of animals , species composition is mainly Palaearctic ,which accounts for 80 .15% of the total species while only 19 .85% of the total species belong to Oriental;from an aspect of distribution patterns of wild terrestrial vertebrates in China ,the subarea contains 11 distribution patterns ,in w hich the highland type is absolutely dominant and accounts for 32 .06%of the total species .
