【摘要】 关于十二经脉的循行分布，目前通识性观点突出表达十二经脉在人体体表呈现纵向分布。但如此定位则难以解读三阴三阳“关、阖、枢”理论和《素问·热论篇》外感热病六经传变理论。通过梳理《黄帝内经》中相关内容，提出经脉在人体除呈现纵向区域化分布外，亦存在着表里层次分布特征。这一认识的形成系源于身形组织与经脉的结合，即太阳主皮，阳明主肉，少阳主骨；太阴主脾胃，厥阴主肝，少阴属心。经脉与身形组织的结合过程，在《黄帝内经》关于热病的辨证体系中有相对清晰的印记。经脉的表里层次分布是三阴三阳“关、阖、枢”理论和六经传变理论形成的基础和前提。更多还原

【Abstract】 Regarding the pathway and distribution of twelve channels, the current general view emphasizes their longitudinal distribution along the surface of the human body. Based on such a positioning, it is difficult to interpret the three yin and three yang "opening-closing-pivoting" theory, and the theory of the six channels transmission of externally-contracted febrile disease. Through combing the relevant contents in The Inner Canon of Yellow Emperor （《黄帝内经》）, it is proposed that, in addition to the longitudinal regional distribution of the channels on the human body, they also exhibit characteristics of layered distribution between the exterior and interior. The formation of this theory stems from the combination of body tissue and channels, that is, the taiyang governs the function of skin, yangming governs the function of flesh, and shaoyang governs the function of bone; taiyin governs the function of spleen and stomach, jueyin governs the function of liver, and shaoyin governs the function of heart. The process of integration of the channels with the body tissues has a relatively clear imprint in the syndrome differentiation of febrile disease in The Inner Canon of Yellow Emperor. The exterior-interior relationships of channels are the foundation and prerequisite for the theory of the three yin and three yang "opening-closing-pivoting" and the theory of the six channels transmission in Plain Questions·Treatise on Heat（ 《素问·热论篇》）.更多还原
