在北朝的墓室壁画中，墓室两壁经常一左一右分别绘制以牛车和鞍马为中心的出行图。本文将就这一特定题材进行研究，探讨北朝壁画墓中的牛车鞍马出行题材的形成渊源，认为该题材开始出现于北魏，到北齐时形成一套制度性的规范。并且这种规范对官员具有约束性的力量，使北齐境内壁画墓中的牛车鞍马题材逐渐从京畿推广到边缘地区。

In the tomb painting of the Northern Dynasties, there were always two paintings drawing an oxcart and a saddle-horse as the center of murals on each side of the chamber walls respectively, and with many attendants encircling the oxcart and saddle-horse, all these factors composed a picture of going out. This paper will focus on the particular theme---a going out picture of oxcart and saddle-horse, studying the formation and origin of this theme in the Northern Dynasties. And the conclusion is that this theme appeared in Northern Wei, becoming a set of norm in the Northern Qi. And this kind of norm had a strength of stipulation to the officials, making the going out picture of oxcart and saddle-horse’s theme expand from the capital of Northern Qi to edge region gradually.
