【摘要】 2003年9月~2004年8月对南充城区的鼠形小兽群落进行研究,应用聚类分析将其划分为3种群落:C1以微尾(Anourosorex squamipes)+褐家鼠(Rattus norvegicus)为主的居民区附近的垃圾地带鼠形小兽群落;C2以微尾+大足鼠(Rattus nitidus)为主的河谷-风景区鼠形小兽群落;C3以微尾+褐家鼠+黑线姬鼠(Apodernus agrarius)为主的校园鼠形小兽群落。其群落多样性指数和均匀性指数均以C3最高,C2次之,C1最低,导致其原因可能与生境和食物丰富度有关。更多还原

【Abstract】 According to the cluster analysis of study from Nanchong in Sichuan Province from September 2003 to August 2004,the structure of small mammal communities can be divided into three types: C1 plantation communities dominated by Anourosorex squamipes and Rattus norvegicus near the residential area;C2 riverside and beauty spot communities dominated by Anourosorex squamipes and Rattus nitidus;C3 campus communities dominated by Anourosorex squamipes and Rattus norvegicus and Apodernus agrarius.The C3 have the highest species diversity index and evenness index,C2 the enxt,and C1 the lowest更多还原
