| 摘 要： | 大沙鼠（Rhombomys opimus）是中亚荒漠、半荒漠草原的典型鼠种，在荒漠草原多呈不连续的岛状分布，多集居于白刺（Nitraria sibirica）、盐爪爪（Kalidium foliatum）丛生的沙地或风成沙丘上的灌丛之间，是农、林、牧以及卫生防疫的重要害鼠。对其种群数量动态目前只有黄健和张大铭（2004）采用Leslie矩阵进行了研究。本文探讨了大沙鼠种群密度与降水量的关系，为其种群动态提供基础资料。 |
| 关 键 词： | 大沙鼠 种群密度 降水量 预测 |

| Abstract: | Based on population surveys of great gerbil(Rhombomys opimus)by blocking up the mouseholes and inspecting the opened ones conducted in three different habitats in Tengenor,Damaolianheqi,Baotou City of Inner Mongolia in February,April,June,August,October and December from 2003 to 2005,relationship between density of the great gerbil and rainfall was analyzed.Results showed that population densities of the great gerbil vary with seasons and years,and its density curves have a single peak value every year.A regression equation Y8=-8.7202 + 0.8806X(df=16,r=0.5394>r0.05=0.468)resulted from analyzing the relationship of the density to the rainfall the previous month indicates that the population size of the great gerbil was positively related to the previous month's rainfall.The density occurring in August and October can be predicted by that in April.The forecasting models for the density in August and October are Y8=-1.0925+2.6133X4(df=6,r=0.9776>r0.01=0.834)and Y10=-0.2097+2.4992X4(df=6,r=0.9672>r0.01=0.834)respectively. |
