| 摘 要： | 通过对分布于横断山区大绒鼠的肥满度进行测定，以探讨大绒鼠肥满度与环境之间的关系为主要研究目的，采用体重与体长立方的比值（K=100 W/L3）作为测定肥满度的指标。结果表明：大绒鼠雌雄鼠肥满度之间差异不显著,大绒鼠不同年龄组之间肥满度差异不显著。大绒鼠不同季节的肥满度差异极显著，肥满度季节变化趋势为：春季较低,夏季最高,秋季较高,冬季较低。大绒鼠的肥满度在不同季节表现的变化模式与其生存的低纬度高海拔、年平均温度较低的横断山区密切相关。 |

| Abstract： | Relative fatness was measured in Eothenomys miletus in hengduan mountains. In order to study the relationship between body status and circumstances in E. miletus, the relative fatness in E. miletus was calculate by empirical formula (K=100 W/L3). The results indicated that there were no significant sexual differences with respect to relative fatness; the relative fatness showed no significant differences in the groups with different ages; but the relative fatness showed significant differences in different seasons. Seasonally trends were lower in winter and lowest in spring; then highest in summer and higher in autumn. The changes pattern of E. miletus in different seasons were related to their microenvironment such as low latitude, high elevation, and lower average ambient temperature in Hengduan mountains. |
