目的　为与海马结构形态改变相关的疾病提供线性测量指标。  方法　选取31例成人头部横断面标本，观测海马面积、海马矢径、海马横径、颞叶钩回间距，数据经标准化处理后分析海马矢径、海马横径、颞叶钩回间距与海马面积的相关性。  结果　海马结构横径标准化前后性别间有差异（P<0.01）；数据经方差齐性检验后，利用Pearson相关分析显示：海马矢径标准化前后与海马面积显著正相关（P<0.01）；海马横径标准化前后与海马面积呈显著正相关（P<0.05）；钩回间距标准化前后与海马面积呈显著负相关（P<0.01)。  结论　海马矢径、海马横径、钩回间距可以作为研究海马形态变化的线性参考指标。

Objective　To provide a linear measurement for the disease associated with the hippocampus morphological changes.　Methods　The area, the sagittal diameter, the transverse diameter of hippocampi, and the spacing of the temporal lobe uncus were observed on 31 specimens, as well the correlation of them was analyzed after standardized processing.　Results　There was a significant sex difference (P<0.01) for the HPF transverse diameter around standardization. Homogeneity test of variance process and standardized processing, with Pearson correlation analysis, showed the remarkable positive correlation between area and the sagittal diameter of HPF around standardized processing（P<0.01）, remarkable positive correlation between area and the transverse diameter of HPF (P<0.05）, and remarkable positive correlation between area and the spacing of the temporal lobe uncus（P<0.01).　Conclusions　The hippocampus diameter, the sagittal diameter, the hook spacing can be used as linear indexes for exploring of hippocampus morphological changes.
