摘　　要：目的探究陕西省境内洛河与渭河交汇的三角洲地区黄鼠的染色体数目,为分类鉴定提供依据。方法采用骨髓细胞直接制备染色体的方法,经制片后镜检。结果共观察2只黄鼠标本的47个细胞,其中染色体数目为2n=38的细胞有45个,占观察总数的95.74%。结论陕西省境内洛河与渭河交汇的三角洲地区黄鼠应为阿拉善黄鼠。Objective To investigate the chromosome number of ground squirrels in the delta at the intersection of Luo River and Wei River （Wei-Luo Delta） in Shaanxi province, China and to provide a basis for the classification and identification of Spermophilus alashanicus. Methods The chromosome karyotype of ground squirrels was studied by microscopic counting of bone marrow cell chromosomes. Results Forty-seven cells of two ground squirrels were investigated, of which 45 （95.74%） were observed with chromosome number 2n=38. Conclusion The ground squirrels in the Wei- Luo Delta of Shaanxi are Spermophilus alashanicus
