摘要
本文从所获的达乌尔黄鼠样本中随机抽出153只,其中雄鼠70只,雌鼠83只,以晶体干重为依据可分为3个年龄组,并与臼齿磨损程度,体长、体重等指标作相关分析,有助于了解泰来县鼠疫疫源地区达乌尔黄鼠的种群结构.
The Spermorphilus dauricus in this article were caught in Tailai County. One hundred and fifth -three are taken as random samplings,70 males and 83 females. They are divided into three groups according to the measures lens weight. We' ve also made related analysis together with the index of the wear of molars,the body length and body weight. These may help us to know the Spermorphilus dauricus's population structure and the index number of breed in Tailai. They may also provide important basis for the study of age assessment.
