Abstract: In order to understand the relationship between the characteristics of animal community and host animals virus-carrying condition of hemorrhagic fever with renal syndrome (HFRS), night trapping method was used to capture animals. We recorded the murids and their living environments, extracted RNA and genotyped of Hantavirus (HV) carried by the murine-like animal. The biological diversity in vary kind of habitats was analyzed by BIOTOOLS, and that the correlation between biodiversity and animal carrying HV was analyzed by using SPSS.The result showed that there was significant difference in the biological diversity as well as the index of virus carriage of host animal in different habitats(F=7.463，P<0.01；F=7.892，P<0.01). Indexes of virus carriage in farmland and wasteland were high, whereas the animal carrying HV was not found in mountain land; biodiversity index in mountain land was higher than that in farmland and wasteland. There was significantly negative correlation between virus-carrying rate of host animal and biodiversity index(Shannon-Wiener(H′),Margalef(dMa) and Evenness(E)),(R2=0.4255,P<0.01; R2=0.4368,P<0.01; R2=0.3321,P<0.05) whereas with which was positive correlation Simpson′s Dominance(λ). The mountain land has a inhibitory effect on the transmission of HV among host animals, extreme abundant biodiversity is beneficial to the stability of animal community structure, which can help to reduce the risk of passing the virus on. The areas in which have low biodiversity community as well as have obvious dominance are dangerous for HFRS, we should strengthen the prevention and control.
