摘　　要：抽样调查了520例(男343例,女177例)江西赣州客家人和203例(男68例,女135例)广东梅州客家人的手足4项人类群体遗传学指标(拇指类型、环示指长、指甲类型、足趾类型).结果表明:(1)两地客家人的手足4项指标类型的出现率在性别之间的差异均不具有统计学意义(p>0.05);(2)4项指标在两地客家人中的男性群体间和女性群体间的差异没有统计学意义(p>0.05);(3)两地客家人与其他地区的10个族群相比,直型拇指出现率均处于较低水平,非扁型指甲和拇趾长出现率均处于中等水平;(4)聚类分析结果表明,江西赣州客家人具有典型的北方族群特征,广东梅州客家人具有南方族群特征.The comparison of four indexes of human population genetics （including thumb type, palmar digital formular, fin- gernail type and plantar digital formular） was conducted on two Han nationality groups, including 520 Hakka individuals （343 males, 177 females） from Ganzhou of Jiangxi province and 203 Hakka individuals （68 males, 135 females） from Meizhou of Guangdong province. The results were as follows ： （ 1 ） There were no statistic sex differences on the frequencies of four indexes for each group （p 〉0.05 ） ; （2） For each sex, there were no statistic differences on all indexes between two focal groups （p 〉0.05 ） ; （3） Compared with other ten ethnic groups, the frequency of straight thumb showed a relatively lower level whereas the frequency of the long-shaped and square-shaped fingernail and the big toe displayed a middle level; （4） Based on the results of cluster analysis, Hakka people in Ganzhou of Jiangxi province had typical characters of northern groups, whereas Hakka people in Meizhou of Guangdong province had characters belonging to southern groups.
