Abstract: Objective:To study some feature of the rodent population in Dongling Mountain,Western Beijing.Methods:7 species of rodents,568 individuals were captured by snap-traps in three different ecological habitats in the region from June 1998 to May 1999.Results:The structure of rodent communities were simple,the dominant species were quite outstanding.There were 5 species in the forest habitat and capture rate was 4.06%,of which,Apodemus peninsulae,Clethrionomys rufocanus and A.agrarius were the dominant species.Five species in the shrubs habitat,the capture rate was 5.19%,and A.agrarius,C.rufocanus and A.peninsulae were the dominant species.Six species in farmland habitat,the capture rate was 6.53%,and A.agrarius,Mus musculus and <>Cricetulus triton were the dominant species.This paper dealt with some population parameters,included biomass,age structure,relative fatness,reproductive index,sex ratio,and breeding length of 7 rodent species in different habitats.Conclusion:The population of A.agrarius may increases.
