中文摘要	2002--2010年, 在内蒙古阿拉善荒漠区采用铗日法对禁牧区和轮牧区子午沙鼠(Meriones meridianus)种群数量进行调查, 分析子午沙鼠种群数量的季节和年间变动规律, 同时利用线性回归分析进行种群预测. 结果表明, 9年共捕获子午沙鼠2 360只, 占总捕获量的39.68％, 说明子午沙鼠为该地区的优势鼠种. 在轮牧区, 2008年子午沙鼠种群数量显著高于其他年份, 捕获率达到13.25％, 为最低年份的57倍, 其他年份捕获率均未超过 3％; 在禁牧区, 子午沙鼠在9年中的种群数量波动较小, 均低于4％. 线性回归分析表明, 用当年4月子午沙鼠捕获率预测7月捕获率, 预测的准确率较高, 可为啮齿动物防治提供实践指导. 禁牧区的预测模型为y_1为 0.384 9+1.085 4x_1(P=0.046, y~2=0.456, f=8); 轮牧区的预测公式为y_2=-0.974 1+2.397 3x_2(P<0.001, =0.925, d, f=8)
英文摘要	The dynamics of Meriones meridianus population both in ban-grazing and rotation-grazing area were studied by live trap method in Alxa desert from 2002 to 2010, and further analysed its seasonal and year variation. Meanwhile, a prediction model for M. meridianus population was achieved by applying the linear regression analysis. The results showed that atotal number of 2 360 M. meridianus were captured during experimental period, amount to 39. 68% captured rat, which indicated M. meridianus was the dominant species in this area. In rotational grazing area, the capture rate of M. meridianus was 13. 25% in 2008 was 57 times than the lowest population, and significantly greater than the other years. In ban-grazing area, the population of M. meridianus exhibited a small fluctuation and capture rate, was lower than 4% each year. Linear regression analysis showed that the capture rate in July can be estimated by the capture rate in April, and the prediction accuracy was very high. The prediction function for ban grazing area was y_2=0. 384 9+1. 085 4x_1 (P=0. 046,r~2 =0. 456,df=8), and the prediction function for ban grazing area was y_2 =-0. 974 1+2. 397 3x_2 (P<0. 001,r~2 =0. 925,df=8)
