摘　　要：为了研究黑龙江省东南部林区啮齿动物群落结构和数量季节变动规律,利用铗日法采集标本以及林业部门和各林场提供的数据,于2008年1月-2010年12月通过实地调查。结果表明,黑龙江东南部林区共有啮齿动物21种,隶属3目、8科、16属,占黑龙江省的70%。其中古北界17种(占80.95%),广布种4种(占19.05%),在动物区系组成上以古北界为主。季节变动夏季数量最高,春季最少。而年间变动较为稳定。在捕获的数量上看棕背鼠平(Clethrionomys rufocanus)为优势种。In order to study the regular pattern of seasonal variations of community structure and number of rodent in the southeast forests of Heilongjiang Province,China,and to provide scientific evidence for the department of forestry to master the outbreak regularity of rat pest from January,2008 to December,2010.We carried out a on-the-spot investigation and gathered samples using clip day methods,combining the data provided by forestry centers and the departments of forestry.The findings showed that there were 21 kinds of rodents,belongs 3 orders,8 families,and 16 categories,which accounted for 70% of rodents in Heilongjiang and in which there were 17 kinds of palearctic realm（accounting for 80.95%）,4 kinds of dispersed species（accounting for 19.05%）.In the composition of animal fauna palearctic realm was dominant.The number of rodents was the largest in summer in terms of seasonal variations,the smallest in spring,stable between years.In terms of captured number Clethrionomys rufocanus was the dominant species.
