摘　　要：自2009年7-11月及2010年3-11月,对千岛湖2个岛屿标志重捕的169只社鼠(Niviventer confucianus)的巢区面积进行了季节、性别及岛屿间差异的分析.结果表明:季节间社鼠巢区面积具有显著差异(P<0.05);繁殖季节的春季及秋季社鼠雌雄个体间的巢区面积无显著差异(P>0.05),仅在非繁殖高峰期的夏季具有显著差异(P<0.05);岛屿间社鼠巢区面积不具有显著差异(P>0.05).因此,岛屿状态下季节及性别对社鼠巢区面积具有显著的作用,并且与陆地状态下鼠类巢区面积的研究具有一定的差异性.From July to November in 2009 and March to November in 2010,it was analyzed the home range area about the effecy between different seasons,sex and islands of 169 Niviventer confucianus captured from two islands at Thousand Island Lake.The results showed that： home range size had a significant difference in seasons（P0.05）;home range area had no significant differences between male and female in the peak of breeding season（P0.05）,but there was a significant difference in the peak of non-breeding period,in summer（P0.05）;home range area had no significant differences between islands（P0.05）.In short,season and sex had independent role to home range area of the Niviventer confucianus on the island state,and there were some differences between the presented results and the research under the land area about the home range area of rodents.
