飞鼠越冬巢穴材料导热系数实验研究

Thermal Conductivity of Nest Materials of Siberian Flying Squirrel( Pteromys volans) During Winter

针对飞鼠冬季选取的栖息地巢穴材料的导热系数开展研究,是实现飞鼠越冬巢穴内部热环境研究的重要理论前提。本文对飞鼠越冬选取巢穴材料的导热系数开展实验研究,将巢穴材料分为树洞材料和巢材两种。研究结果表明飞鼠越冬选取树洞的导热系数在0.145～0.174 W/(m·℃)间。而飞鼠越冬时选取巢穴内巢材的导热系数平均值为0.0446 W/(m·℃)。二者结合可以使冬季巢穴内保温隔热效果显著,在飞鼠越冬中发挥着重要的作用。

Study of the thermal conductivity of nest materials used or collected by Siberian flying squirrel(Pteromys volans)during winter is can be an important prerequisite for the study of the internal thermal environment of the nest.We investigated the thermal conductivity of nest materials chosen by Siberian flying squirrel during winter.The nest materials included the tree hole and inner-nest materials.The thermal conductivity of the tree hole was 0.145-0.174 W/(m·℃)and the average thermal conductivity of the inner nest material was 0.0446 W/(m·℃).The thermal insulation effect of the nest,which combined the tree hole and inner nest materials,was important to the winter survival of Siberian flying squirrel.
