摘　　要：中缅树鼩为东洋界特有的小型哺乳动物,具有特殊的进化地位,在生物医学上被广泛采用为实验动物。本论文以中缅树鼩(Tupaia belangeri)为研究对象,从个体、组织及分子水平对中缅树鼩的产热特征及能量代谢进行了系统的研究。得到以下成果:首次从生理生态学角度支持了树鼩由南向北扩散的“岛屿起源”假说,温度是限制中缅树鼩继续向北扩散的主要因素;中缅树鼩的产热特征及能量代谢具有季节性和日节律变化,温度和光周期对产热特征及能量代谢具有显著影响。研究成果为东洋界小型哺乳动物的生理生态适应模式与对策提供了理论依据。Tree shrew (Tupaia belangeri) is a small mammal in Oriental endemic with special evolution status, and it has been widely used in biomedicine as experimental animal. In this paper, we used T. belan-geri as the research object, thermogenesis and energy metabolism were measured in system of T. belangeri from individual, organization and molecular levels. The following results were obtained: for the first time to support the “island origin” hypothesis that T. belangeri diffused from south to north from the physiological ecology angle, and temperature is the major factor which limited T. be-langeri continued northward diffusion;thermal characteristics and energy metabolism in T. belan-geri with seasonal and diurnal variation;temperature and photoperiod had significant effects on its thermal characteristics and energy metabolism. Research results provide a theoretical basis of phy-siological ecological adaptation model and countermeasures for Oriental small mammals.
