陕西秦岭平河梁自然保护区小型兽类的组成与分布

Species and Distribution Patterns of Small Mammals in the Pingheliang Nature Reserve of Qinling Mountain, Shaanxi

    摘要
  • 摘要: 2005年9月利用铗日法辅以陷阱法对位于秦岭山脉南坡东段的平河梁自然保护区及牛背梁自然保护区小型兽类进行了调查，共设置采集点10个；2 460铗日中共捕获小型兽类689只，隶属于3目6科19属27种（另有两种鼢鼠和一种鼯鼠系其他手段捕获），平均捕获率28.01%。对捕获的27种小型兽类生态和垂直分布进行分析结果表明：平河梁保护区3个群落的Shannon-Weiner多样性指数在2.9288—3.3639之间，Pielou均匀性指数在0.7669—0.8602之间。在上述调查的基础上，结合前人对邻近地区的调查，据一些物种的分布特点，订出平河梁自然保护区小型兽类的名录，计48种，结果显示秦岭南坡东段小型兽类的物种多样性和丰富度要高于秦岭其他地区。另在考察中采集到白尾鼹(Parascaptor leucura)、小纹背鼩鼱(Sorex bedfordiae)、斯氏鼢鼠(Myospalax smithii)、川西白腹鼠(Niviventer excelsior)，在秦岭山区尚属首次记录。还整理了秦岭南坡小型兽类名录，认为秦岭南坡有小型兽类55种，在动物地理区划上应属于西南区。

     

    Abstract: This paper presents species and distribution patterns of small mammals in the Pingheliang and Niubeiliang Nature Reserves on the south slope of the eastern part of Qinling Mountain. This work was conducted in September, 2005. A total of 689 individuals were captured on 2460 trap-days. Twenty-seven species of small mammals, representing three orders, six families and 19 genera, were recorded from 10 study sites. The average rate of capture was 28.01%. Ananalysis of ecological and vertical distribution of the mammals showed that the Shannon-Weiner diversity index in three communities was 2.9288-3.3639
    and the Pielou evenness index was 0.7669-0.8602. Based on this survey and former studies in other nature reserves and areas surrounding Qinling Mountain, the small mammal fauna of Pinghe    liang Nature Reserve includes 48 species of three orders, 11 families and 33 genera. This presents a higher diversity and richness of small mammals on the south slope of the eastern part of Qinling Mountain than in other areas of the mountain. Parascaptor leucura, Sorex bedfordiae, Myospalax smithii and Niviventer excelsior caught in this investigation are the first records of these species on Qinling Mountain. A list of 55 small mammals from the south slope of Qinling Mountain is also given following a general review. The south slope of Qinling Mountain should be classified within the Southwest Region in the zoogeography of China.
