摘　　要： 目的:研究300名正常白族人的手掌主线分布,为人类学、医学、遗传学提供正常参数。方法:在知情同意手续下,捺印调查对象的手纹。结果:A主线,Ⅲ型占96%、Ⅴ型2.17%、Ⅰ型1.83%;B主线,Ⅴ型93%、Ⅶ型7%;C主线,Ⅴ型44.5%、Ⅶ型40.67%、Ⅸ型11.67%、O型3.16%;D主线,Ⅸ型47%、Ⅶ型46%、Ⅺ型7%。主线分布以35′5″7、35′79、35″79为主(占76.67%)。39.67%的个体双手主线对称分布,以35′5″7为主(15%)。MLI平均为6.25±1.37,MLIT为22.52±3.00,二者均为男性大于女性(P<0.05),无手别差异(P>0.05)。3.17%的个体缺失c三叉。结论:白族人的手掌主线和其他民族有共性又有其特异性。 Objective： To study the distribution of palmar main lines on 300 normal people belonging to the Bai Nationality, and to provide normal parameters for this feature in anthropology, medicine and genetics. Methods： The ink prints of fingerprints and palmar patterns were obtained with informed consent. Results： For main line A, type Ⅲ is 96%, type Ⅴ is 2.17%, and type Ⅰ is 1.83%. For main line B, type Ⅴ is 93%, and type Ⅶ　is 7%. For main line C, type Ⅴ is 44.5%, type Ⅶ is 40.67%, type Ⅸ is 11.67%, and type O is 3.16%. For mainline D, type Ⅸ is47%, type Ⅶ is 46%, and type Ⅺ is 7%. The main types of A. B. C. D main line formula are 35′5″7, 35′79 and 35″ 79 （76.67%）. Bilateral symmetry of the A.B.C.D main line formula is 39.67% with the major type being 35′5″7（15%）. The average value of MLI is 6.25 ± 1.37 （SD）, and MLIT is 22.52 ± 3.00 （SD）. Both of MLI and MLIT exhibit significant difference between the sexes（ P 〈 0.05）, but have no significant difference between left and right hands（ P 〉 0.05）. Exactly 3.17% individuals have no C triangle. Conclusions： The distribution of palmar main lines in Bai nationality peoples has common characteristics with other nationalities, but also reflects different characteristics.
