Abstract: The rodent community division were studied in Huangnihe forest region, Jilin Province, from June to July 1988．According to the forest condition We divided the rodent communities into 21 habitat types，and On the basis of species similar coefficient and Iterative inductive Cluster divisianal method．5 rodent communities were formed : Apodemus peninsulae+ Clethrionomys ruyocanus community A．peninsulae community; A.agrarius+A．peninsulae community, Microtus fortis +A．agrarius Community and C.rufocanus+community. Among the C.rufocanus community．A.peninsulae+C.rulocanus community and A．agrarius+A. peninsulag community are respectively the representative communities in coniferous belt．mixed forest of Canifer and broadleaf．and broadleaf belt．

Key words: forest area, Rodent community, Species similar coeficient, Interative inductire cluster divisional method

摘要： 1988年6-7月，作者在吉林省黄泥河林区对森林鼠类群落划分进行了研究。将林区划分2个栖息地类型，依据物种组成相似系数及递归群划分怯，划分出5个鼠类群落： 即大林姬鼠+棕背好群落；大林姬鼠群落，黑线姬鼠+大林姬鼠群落；东方田鼠+黑线姬鼠群落和棕背好群落，并进行了讨论.
