Abstract: Some ecological characteristics of city's C.migratorius were discussed and analyzed by rodent survey in 11 cities in Xinjiang and tested in the laboratory. Average capture rates was 3.67%(630/16741)and it takes 26.26% of the whole rodents and second only to Mus. musculus .The population density and percentage of specific composition showed old city>new city>suburb;earth and wooden house>old floor board storey>cellar>brick housa,Invasion of Rat.norvegicus and rise of percentage on new building in old cities could cause percentage of C.migratorius to decline,and urban deratization campaign or developing on new cities might cause the percentage to increase.The results show that the animal renews oler four times every year,in which there is foetol marks with an average of 7.1 marks per littera,the age of sexual maturity is about 50 days,and the sex ratio is 0.544.Peaks of population density were May and November in a year,which is higher than rural area. It has been found firstly that the rodent can hibernate in condition of low temperature.
