南充市金城山小型兽类组成

Species Composition of Small Mammals in Jinchengshan

采用铗日法,笔者对南充市高坪区金城山的住宅区、河谷、农田、和林区四类生境中的小型兽类种类组成进行了调查分析,结果表明,金城山共有啮齿目的小泡巨鼠(Leopoldamys edwardsi)、黄胸鼠(Rattus flavipectus)、褐家鼠(Rattus norvegicus)、社鼠(Niviventer confucianus)、针毛鼠(Niviventer fulvescens)、黑线姬鼠(Apodemus agrarius)、大足鼠(Rattus nitidus)、小家鼠(Mus musculus);食虫目的微尾鼩(Anourosorex squamipes)和云南鼩鼱(Sorex excelsus)和翼手目的扁颅蝠(Tylonycteris pachypus)及东亚伏翼(Pipistrellus abramus)12种小型兽类.种类组成呈现小泡巨鼠为主,黄胸鼠和褐家鼠为次,其他种类较少的格局.种类组成在不同的生境有所不同.

The species composition of small mammals in Jinchengshan was studied,which is located in the east of Nanchong city,northeast of Sichuan province. Trapping night method was used to collect these animals in four types of habitats,including residence,riverside,farmland and forest zone. The results showed that there were twelve species of small mammals in Jinchengshan：Leopoldamys edwardsi,Rattus flavipectus,Rattus norvegi-cus,Niviventer confucianus,Niviventer fulvescens,Apodemus agrarius,Rattus nitidus,Mus musculus,Anourosorex squamipes,Sorex excelsus,Tylonycteris pachypus,pipistrellus abramus. Leopoldamys edwardsi are the dominant species. The species composition of small mammals varied in different habitats.
