摘要
采用标志重捕法在海拉尔东山上捕捉达乌尔黄鼠,确定年龄(根据牙齿磨损程度)、性别、数量,编制静态生命表以推测种群发展动态。研究表明,该地区中Ⅰ龄鼠占66.7%、Ⅱ龄鼠占20%、Ⅲ龄鼠占13.3%,年龄结构呈金字塔型,属于增长型种群,群体雄雌比例为1∶1.14,接近1∶1,种群中雌性略大于雄性。
The paper used mark-recapture method, and caught Spermophilus in Hailar Dongshan to determine the age （tooth wear）, gender, quantity, preparation of a static life table of population development inferred dynamicstudies. The result showed that the region I age mice accounted for 66.7%,Ⅱage of rats accounted for 20%, Ⅲ age mice accounted for 13.3%, age structure pyramid type, belonging to the growth of population, groups of female and male ratio of 1：1.14, close tol：l populations, females slightly larger than the male.
