中文摘要	2002-2008年,在内蒙古阿拉善左旗嘉尔格勒赛汗镇天然荒漠草地中,采用铗日法对划区轮牧样地的啮齿动物种群数量进行调查.每年的4,7,10月的上旬进行野外调查取样,每次取样时随机选择4个铗捕样方,每个样方10 hm2,布设500铗日,每铗线100铗,铗距5 m,铗线距50 m.利用灰色关联度法对群落中主要鼠种的捕获率与年降水量的关联度进行分析.结果表明,各年度的啮齿动物捕获率与年降水量显著正相关(r=0.390 5,P<0.05).年降水量与群落中主要鼠种的关联度大小顺序为:三趾跳鼠>五趾跳鼠>小毛足鼠>阿拉善黄鼠>子午沙鼠>黑线仓鼠.群落中跳鼠对降水量的反应较明显,三趾跳鼠和五趾跳鼠的灰色关联系数分别为0.855 6和0.818 9;子午沙鼠和黑线仓鼠对降水量的反应较弱,关联系数仅为0.706 7和0.706 4
英文摘要	Rotational grazing is a main utilization types in the Alxa desert grasslands. The live trap method was used to investigate the rodent population in the rotational grazing grassland area of Jiaergelesaihan town during 2002 to 2008.The field survey was carried out at the beginning of April, July, and October in every year. Four sample plots with the size of 10 ha were randomly chosen every time.500 clips were put in the each plot with 100 clips in a line, and the distance between clips was 5 m and the distance between lines was 50 m.The grey correlative degree was applied to determine the relationship between the capture rate of main rodent species and annual precipitation. This study showed that total capture rate of rodent was significant positive correlation with annual precipitation(r=0.390 5,P<0.05), and the order of correlative degree between main species and annual precipitation was Dipus sagitta>Allactaga sibirica>Phodopus roborovskii>Spermophilus alaschanicus>Meriones meridianus>Cricetulus barabensis. The response of Jerboa to the precipitation was more obvious than other species. The grey incidence coefficient of D.sagitta and A.sibirica with precipitation was 0.855 6 and 0.818 9, respectively. The response of M.meridianus and C.barabensis to the precipitation was weak, indicating that the grey incidence coefficient of them was 0.706 7 and 0.706 4
