2007年秋季和2008年春季,采用夹夜法对千岛湖14个岛屿进行小型兽类群落组成调查,研究其群落空间分布格局及其影响因素.两季度共布置夹16 800只,捕获小型兽类1 037只,隶属2目2科7属11种.其中啮齿目(Rodenria)鼠科(Muridae)9种,食虫目(Insectivora)鼩鼱科(Soricdae)2种.结果显示:千岛湖小型兽类群落呈非随机分布格局;嵌套分析表明,千岛湖岛屿小型兽类群落呈现极显著嵌套格局,植物丰富度和生境专属性两项参数对其嵌套格局的形成具有显著影响,从而使适应力强的物种能够在多样的环境中生存,而适应力弱的物种则局限在特定的环境中.由于取样强度差异会过高地估计嵌套程度,故在研究中应尽量去除取样强度的干扰.

During autumn 2007 and spring 2008, we surveyed 14 islands, with a total of 16800 traps, for small mammals in Qiandao Lake, Zhejiang to determine their community distribution. The captured small mammals belonged to 11 species, 7 genera, 2 families and 2 orders, including 9 species of Murids (Muridae) , and 2 species of Soricds (Soricdae) . The results showed that the small mammals present a non-random nested pattern in assemblage on the islands. In terms of larger scale perspective, the species of high adaptability were able to adjust to the various environments, while ones of low adaptability only survived in particular circumstances. Plant species richness and habitat specificity of the species were the main ecological factors that influenced the formation of this pattern.
