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.
摘要: 本文根据1989~1992年新疆11个城市鼠类调查和实验室结果,讨论分析了城市灰仓鼠的某些生态学特征。捕获率3.76%(630/16741),占捕获总数的26.26%(仅次于小家鼠),其密度和构成比依次为老城>新城>城郊,土木建筑>旧地板楼>地下室>砖平房。褐家鼠的迁入或老城新建筑结构比例的上升,可导致灰仓鼠构成比的下降;灭鼠或新城发展,可促使构成比的上升。在城市,灰仓鼠一年四季均可繁殖,窝数在4窝以上,平均胚胎数7.1只,性成熟日龄50天左右,性比0.544,年内种群密度高峰在5月和11月,总密度明显高于农区。首次证实灰仓鼠在低温条件下可冬眠。
