摘　　要：目的分析宁夏回、汉族人群指纹模式各类型的分布特征。方法采用随机整体抽样方法分析宁夏回、汉族指纹样本共计614份，其中回族262人（男性129人，女性133人），汉族352人（男性206人，女性146人）。结果固定某指为弓型纹（A）后，相同的花样类型同时出现于另外9指的几率明显增高，而尺侧箕型纹（U）与斗型纹（W）的出现率则明显降低；而当固定某指为u后，u同时出现于另外9指的几率明显增高，而w的出现率相较总体样本出现率明显降低，A的出现率受影响的程度较小；当固定某指为w后，情况恰好相反。这种趋势在宁夏回、汉族以及不同性别问都存在，且无显著性差异。结论指纹的模式影响，即不同手指指端花样类型的构建及出现率彼此关联，在宁夏回族、汉族和两性别问普遍存在。Objective To analyze the occurrence and probability of the manifestation of finger pattern types in Han and Hui ethnics from Ningxia. Methods In this study, dermatoglyphic traits in Hui 262（male 129, female 146） and Han 352（male 206, female 146） were analyzed. Results In the entire sample, both Hui and Han were located around the ulnar loop and the whorl. Whereas this arrangement was significantly and typically different in pattern influence cases. When the arch occurred on one of the fingers, this pattem type was also much more frequent on the other nine fingers, whereas whorls were much less common. When there was an ulnar loop on one of the fingers, the frequency of the ulnar loop on the other nine fingers was higher, whereas the frequency of the whorl was lower, than in the entire sample. The frequency of the arch was not influenced by the occurrence of the ulnar loop on other fingers. However, the tendency was the opposite when there was a whorl on one of the fingers. Conclusion The formation and occurrence of pattern types on certain fingers is closely related to the pattern type on the other fingers, which is pattern influence. The pattern influence shows that if a given pattem type is present on one of the fingers, then, in these cases, the frequency of pattern types on the other nine fingers typically is different from that in the entire sample. Pattern influence was found in both Hui and Han nationalities, and in both sexes.
