摘    要:本文依据1988年4~6月在黑龙江省齐齐哈尔华安区和泰来县东方红林场捕获77只鼢鼠标本材料(51只雄性、26只雌性),研究它们的性比和繁殖情况。捕获的材料表明其性比是雄性比雌性多。繁殖指数依下列公式计算I=NE/P其中I表示繁殖指数,P为总捕获只数,N为孕鼠数,E为平均胎仔数,它们表明鼢鼠繁殖强度的季节变化及原因。

关 键 词:东北鼢鼠  种群结构  繁殖  胴体重

Abstract:This paper deals with the populational composition and breeding characteristics of Manchurian Zokor ( M yoapalas psilurus) in the Huaan District of Qiqihar and Dongfanghong forest farm of Tailai county, Heilonjiang province, from April to June, 1988. Among the 77 specimens collected, are 51 males and 26 females. The sex ratio and reproduction status of Manchuran Zokor are as follows. The reproductive indices are calculated by the following formular: I=NE/ P. I. representing the reproductive index; P. the total number of capture; N.the number of the preg-nant ones; E. the average number of foetuses. They snow the annual changes and its reasons for reproductive intensity of Manchurian Zokor.
Keywords:Mgoapalas psilurus  population structure  breeding  body weight
