本文通过对北魏中晚期云冈石窟与龙门石窟中具有代表性的窟龛造像的对比研究,来探讨北魏中晚期各种文化的交融。从最能表现窟龛造像特点的石窟形制及窟内造像这两个方面作为切入点进行比较。通过一系列对比研究,明晰了在我国的石窟艺术不断中国化的进程中,始终有三种文化在不断地交融,正是这三种文化的不断交融,才造就了我国特有的佛教石窟艺术面貌。 In this paper, through comparative study of the representative niche statues of the Yungang Grottoes and the Longmen Grottoes in the middle and later Northern Wei Dynasty, this paper explores the blending of various cultures in the middle and late Northern Wei Dynasty. This paper compares the grotto shape and the cave image which can best represent the niche statues. Through a series of comparative studies, it is clear that in the process of continuous Chinese-style Chinese grotto art, there are always three kinds of cultures that are constantly blending. It is the continuous blending of these three cultures that has created the unique appearance of Buddhist grottoes in our country.
