P>Objective To investigate the heads’ morphological characteristics of the Han nationality in He’nan and to analyze the human head length indicators related to their body height. Methods According to the somatometric measurement handbook(2nd Edition), 7 index including head length，head breadth, face breadth，minimum frontal breadth，bigonial breadth，external biocular breadth，and interocular breadth on head of 1 050 men and women in He’nan Han population adults was measured, while the cluster analysis compariton with other domestic ethnic population was implemented, the equation of linear regression was set up. Results Seven head length indicators on Henan Han male adults were higher than the female. There was a significant gender difference in addition to head width and interocular breadth. In the He’nan Han nationality adults, the 7 head length indicators related to the height presented a linear dependence, especially the bigonial breadth. The cluster analysis showed up adoption societies between the He’nan Han nationality adults and Dongxiang nationality, earthy group, the Baoan (Paoan) nationality,and the Miao minority. Conclusion The 7 head length indicators on He’nan Han nationality adults have the characteristics of the North. The height speculatation error is greater according a single length index, yet it is lower us
