目的:探讨义县汉族人群的指纹特征,为皮纹学研究提供参考.方法:在知情同意情况下按捺523名(男220例,女303例)义县汉族人的掌指纹,分析指纹类型、计数指纹嵴线数.结果:义县汉族人群箕形纹频率最高,男、女分别为51.18％、51.59％,以尺箕纹为主；其次为斗形纹,男、女分别为46.59％、女46.11％,以简单斗形纹为主；弓形纹出现率最低；总指纹嵴数男性为139.48,女性为140.93,性别间不存在差异.结论:义县汉族人群的指纹学特征具有种族特异性,各种指纹型和指纹嵴线数在不同民族及各手指间的分布具有差异性.%Objective: To investigate the hand dermatoglyphic trait of Han nationality in Yixian county of Liaoning province, and provide some reference for dermatoglyphics research. Methods: Fingerprints were obtained with informed consent. There were 523 persons in this sample group, including 220 males and 303 females. The fingerprint patterns were analyzed and the finger ridge count was counted. Results: The most prevalent digital ridge patterns were loops (51. 18% in male and 51. 59% in female), mainly appearing in ulnar loop; The second were whorls (46. 59% in male and 46. 11% in female), par ticularly Ws(simple whorl) was predominant; The least were arches in our samples. The results showed that the total finger ridge count was 139. 48 in males, and 140. 93 in females. There was no significant difference between two genders. Conclu: sion : The results indicate that dermatoglyphic characteristics of the hands of Han nationality in Yixian county show radical specificity and different distributions of fingerprint patterns and finger ridge count between the different nationalities among fingers.
