摘要
目的对大沙鼠巢区面积及巢区间的距离进行探讨,为进一步研究大沙鼠的领域性及活动距离莫定基础。方法2003年10月在内蒙古达茂旗腾格淖尔地区,将连续分布于不同生境的30个大沙鼠巢区位置按1: 100的比例标记于坐标纸上,对大沙鼠巢区面积及巢区间的距离进行了研究。结果大沙鼠的巢区半径和巢区面积在3种生境中没有显著差异;而相邻巢区中心间的距离和边缘的最近距离却不同。生境Ⅱ与生境Ⅰ和Ⅲ之间,无论是相邻巢区的中心距离还是边缘之间的距离均表现出显著性的差异,而生境Ⅰ和生境Ⅲ之间差异并不显著。
Objective Area and adjoining distances of home ranges of great gerbil Rhombomys opimus were investigated to get some information about the territoriality and home range size. Methods In Tengernaoer region of Damaolianheqi, Inner Mongolia in Oct. 2003, 30 continuous home ranges in different habitats of great gerbil were positioned on a squared paper at a scale of 1 ： 100 to measure the home range size and the adjoining distances. Conclusion Results s show that semidiameter and area of the home ranges have no remarkable difference among the three habitats, as indicates that area of the home range has no relationship to the habitats. However the central and nearest distances among home ranges were different. Both the central and nearest distances were significantly different between the home ranges in habitat I and Ⅱ, but not between the home ranges in habitat Ⅰ and Ⅲ.
