【摘要】 <正> 对南充城区的小型兽类群落进行研究,应用聚类分析将其划分为3种群落:C1以微尾鼩+褐家鼠为主的居民区附近的垃圾地带小型兽类群落:C2以微尾鼩+大足鼠为主的河谷-风景区小型兽类群落;C3以微尾鼩+褐家鼠+黑线姬鼠为主的校园小型兽类群落。其群落多样性指数和均匀性指数均以C2最高,C3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 in Sichuan province from September in 2003 to August in 2004,the structure of small mammal communities can be divided into three types: Cl 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 C2 have the highest species diversity index and evenness index, and C3 have lower than that of ones of C2, The C1 have the lowest species diversity index and evenness index.更多还原
