少数民族对中华民族文化的“三维推进”

中华民族文化共同体是一种“巨伞型”的复合结构，具有56条伞骨，撑开来荫蔽八万里，拢起来一柱擎天。它的动力系统具有中原动力和边缘活力互动的特征，没有中原文化的凝聚力和辐射力，多元文化板块的碰撞就可能元气耗散；没有边缘活力，中原的凝聚和辐射就会在单线运动中自我停滞、僵化。为什么中华文明五千年不曾中断？很重要一个原因是，黄河文明与长江文明的相互推移和交融。因为有了长江的阻隔，北方游牧民族入主中原时汉族一些大家族迁移到长江流域，使得长江流域经济、文化快速发展。游牧民族滞留在中原逐渐地被汉化，这就形成了南北的“太极推移”，你推过来，我推过去，汉文化与游牧民族文化愈来愈深地变得“你中有我、我中有你”。在“南北太极”推移的过程中，巴蜀是一个重要的“太极眼”。西南中国是中华民族文化的后花园，是太极推移冲击波的接纳体，有储存文化活化石的功能。中原周边的少数民族在主体民族扩张和南北太极推移冲击波的作用下，携带着自身的文化行李和沿途拿来的文化成品，迁徙到大西南区域。古老的文化成品沉积下来，与百越百濮的土著风俗相调适、相融合，形成了渊源极古、形态极异的文化遗存。如彝族、白族作为村社保护神的土主崇拜依然盛行，叙述神话与民族迁徙的《苗族古歌》广泛传唱，等等。少数民族对于中华民族文化有“三维推进”之功，值得我们以极大的责任感加以深度的认识和发掘。

The Facilitation of Culture of Chinese Nation by Minority Groups

Culture of Chinese nation is like a huge umbrella shading cultures from 56 Minority groups.The driving force for the development of the culture of Chinese nation comes from both the dominant culture and marginal cultures which are all indispensible.Chinese culture cherishes a long history of 5000 years,which is mainly beneficial from the communication between civilizations of the Yellow River and the Yangtze River.When the northern nomadic tribe ruled central China,some big families of han migrated to the Yangtze River basin,which brought the rapid development of Economy and culture to that region.The northern nomadic tribe in the central China became part of Chinese later.Culture of Chinese and that of the northern Nomadic tribe integrated gradually.Ancient Sichuan was an important centre for the integration for the southwest region of ancient China served as the back garden for Chinese culture to store its real fossil part.Minority groups surrounding the central China moved to southwest China with their cultures when the dominant nationality took their former land and the migration of big families of han happened.The ancient cultures of the minority groups were carried on and integrated with those of Baiyue and Baipu nationalities,which eventually formed cultural heritages with long history and diversity.For instance,the worship of Tuzhu,the god protecting villages,is still popular in Bai Nationality and Yi nationality.The Old Songs of Miao Nationality telling myths and stories about the migration is still sung by many people.Cultures of minority groups facilitate the development of culture of Chinese nation in many ways,which worth our further recognition and exploration with a high degree of responsibility.
