Abstract: Objective To elucidate the ecological characteristic of rodents and their medical importance.Methods Using ecology,theoretical and sera epidemiology.Results By a long-period observation,Apodemus(A.) agrarius was the predominant species in the field,and Tscherskia(T.) triton was commonly seen.The total density of rodents had two peaks in a year,the former was in July,the later in October.The density fluctuation of A.agrarius was similar to the total density fluctuation of rodents,but the density of T.triton had only one peak(in July).The fertilization rate of A.agrarius had two peaks(in May and September respectively),and T.triton had one peak.The key factor that affected the density of A.agrarius and T.triton was relative humidity.Natural infection of HV and Ot existed in A.agrarius,T.triton andRattus norvegicus,the density fluctuation of rodents was related with the accidence of HFRS and scrub typhus.
