中文摘要：

为研究栖息于横断山地区的大绒鼠（Eothenomys miletus）身体状况与环境之间的适应关系,本实验对野外、实验室饲养及冷驯化条件下大绒鼠的体重和身体能值进行了测定。结果表明,大绒鼠体重及身体能值存在季节性变化,大绒鼠体重及身体能值的平均值3月最低,6月最高,9月次之,11月开始下降。冷驯化条件下大绒鼠的体重和身体能值均显著低于实验室饲养条件下的,说明在季节变化过程中温度可能是影响其体重和身体能值的一个重要因素。大绒鼠的体重和身体能值的季节变化模式与横断山区的特殊生存环境有关,在一定程度上反映了该物种对横断山特殊环境的生存适应对策。

英文摘要：

In order to study the relationship between body status and circumstances in Eothenomys miletus, body mass and energy contents under different conditions （both infield and laboratory） were measured. The result showed that body mass and energy contents in E. miletus showed seasonal variations. Body mass and energy contents in E. miletus were higher in June and lower in March. Body mass and energy contents in the cold acclimation were decreased significantly to that in the condition of lab-breeding, indicating that temperature is an important factor to influence body mass and energy contents during seasonal changes. The change pattern of body mass and energy contents in E. miletus were related to the adaptation to the environment in Hengduan Mountainous Region.
