Objective To investigate the influence of urbanization on the structure of rodent community in different habitats in the rural areas, and to provide a scientific support for carrying out rodent control. Methods Night trapping method was used to investigate rodent community structure in the rural areas after urbanization. Three hundred traps were set in each sample region. The distance between traps was 5 m and the interval between survey lines was above 50 m. Traps were placed at dawn and collected in dusk. Results The urban-rural encroaching zone became the most important habitat for rodents after urbanization. The number and biomass of house mice increased greatly, while the dominance of voles significantly decreased. In the urban-rural encroaching zone, Rattus norvegicus was the most predominant species and the most pestiferous rodent. In the farmland 500 m away from the town, R. losea was the most predominant rodent and R. norvegicus was the secondary; Bandicota indica, R. norvegicus, and R. losea were the most pestiferous rodents. In the farmland 2 km away from the town, R. losea was the most predominant rodent and Mus musculus was the secondary; R. losea and B. indica were the most pestiferous rodents. Conclusion Urbanization indirectly provides favorable conditions for rodent infestation, with some changes in farmland rodent community. Sustainable management should be strengthened in the face of such changes.
