Abstract: The paper reports the structure of rodent communities, and its seasonal variations in 3 different ecological habitats of Dongling Mountain in Beijing.Trap night method was used, and the rodents were captured each month from June,1998 to May,1999. The results are as follows. 1. In the shrubs habitat,it was Apodemus agrarius + Clethrionomys rufocanus + Apodemus peninsulae community. In the forest habitat,Apodemus peninsulae + Clethrionomys rufocanus + Apodemus agrarius community. In farmland habitat,Apodemus agrarius + Mus musculus + Cricetulus triton community. 2.The indices of biological diversity were different in different habitat and the highest was found in the shrubs habitat. 3. The index of rodent communities similarity between shrub and forest habitats was the highest.
