中文摘要	[目的] 研究阿拉善荒漠区小毛足鼠的繁殖特征及其对种群的调节作用。[方法] 于2006-2011年每年4、7、10月上旬,采用铗日法,对内蒙古阿拉善荒漠区小毛足鼠种群数量及繁殖特征进行了调查。[结果] 调查期间,在该研究区共捕获小毛足鼠502只,其中雌性253只,雄性249只,其平均雌雄性比为1.020.22、平均怀孕率为(37.6314.70)%、平均胎仔数为(5.641.58)只、平均睾丸下降率为(63.0734.29)%、平均繁殖指数为0.770.17)。小毛足鼠捕获数量与平均雌雄性比呈极显著正相关(r=0.99,P<0.01),与平均睾丸下降率呈显著正相关(r=0.94,P<0.05)。[结论] 在阿拉善荒漠区小毛足鼠的繁殖特征参数中,雌雄性比和雄性睾丸下降率对其种群调节起重要作用。
英文摘要	[Objective] The research studied the reproductive characteristics of desert hamster and its adjustment effects on population.[Method] From 2006 to 2011,in the first ten days of April,July and October,the population and reproductive characteristics of desert hamster were studied in Alashan Desert by trap-day method.[Result] During the investigation period,a total of 502 individuals were captured in the study area,among which 253 were female and 249 were male with a mean sex ratio of 1.020.22.The mean pregnancy rate was (37.6314.70)%,the mean number of fetus was 5.641.58,the mean testicular descent rate was (63.0734.29)%,and the mean reproductive index was 0.770.17.Population quantity was very significantly correlated with mean sex ratio in this study area (P<0.01),and significantly correlated with the testicular descent rate (P<0.05).[Conclusion] Sex ratio and the testicular descent rate were the most important factors which have effect on desert hamster population density in Alashan Desert.
