Abstract: Objective To investigate population community and density of rodents,and the plague serological positive. Methods Rodents were caught by the trap and the arch splint, plague antibody was tested with the serum agglutination test. Results 259 rodents belonging to 5 families 9 genera 10 species were collected. The predominan species were Cricetulus barabensis(39.8%), Spermophilus dauricus(29.0%), Mus musculus(13.5%), and Cricetulus triton(11.6%). The community composition of rodents varied with different habitats and places.
