Abstract：During July to August, 2003, an investigation on relative densities of rodent community in Tangjiahe Nature Reserve has been carried out. A total of 18 small mammal species were recorded in the study site. The species with higher relative densities included Apodemus chevrieri (38.95%), Apodemus draco (12.21%) and Niviventer confucianus (12.21%). In the seven typical sites, the relative densities were higher in Chaijiaba (12.00%), Dahuodigou (9.63%), Yaomoyan (7.26%) and Baixiongping (6.29%). But it was much lower in Wenxianhe (3.68%) and Dacaoping (3.00%). Besides, the dominant species were different in every typical sites. However, the reason leading to such distinct result might relate to the abundance level of food.
