%X The population data of rodents in Narenbaolige Sumu,Abaga Banner,Inner Mongolia during 1979-1997 showed annual cyclical fluctuations of Microtus brandti population to a certain degree by cycling index ( S ).There were 10 rodent species,with M.brandti (88 45%) and Ochotona daurica (5 37%) in 1989-1997.There were positive correlation relationships among the total densities (the sum of population densities of rodents in unit area),density of M.brandti and O.daurica ( P =0 0001).The regression model was:the total densities=0 8806+1 0048 (density of M.brandti )+0 8779 (density of O.dauricus ) ( P =0 0001).The diversity and evenness of rodents were influenced significantly by the density of M.brandti .Absolute dominant species was M.brandti in rodent community during 1970-1997.
