“唐末五代代北集团”概念需要进行历史性考察。第一，“以地方藩镇崛起代兴”并不影响代北集团的是否成立；第二，代北集团是一个包括沙陀、昭武九姓胡人、突厥、回鹘、吐谷浑、奚、契絆、鞑靼以及汉族等多种民族成分在内的多民族结合体；第三，代北集团与唐朝统治者存在着“互为作用、资源互利”的关系，集团的形成过程，也就是其与唐朝统治者“互为作用、资源互利”的过程。

The thesis will discuss the foundation of the definition of“the Daibei Group (代北集团)of the five dynasties in the late Tang dynasty”in three folds.Fistly,“rising in the way of local division”does not affect the foundation of Daibei Group;secondly,Daibei Group is a multi -national combination in-cluding multi-national components like the Shatuo (沙陀),Hu (胡)troops,Turk,Huihu (回鹘), Tuyuhun(吐谷浑),Xi(奚),Qibi(契絆),Tartar and Han ethnic group etc.;thirdly,there are “mutu-al interaction and mutual benefit in resources”relationship between Daibei Group and emperors of Tang Dynasty,that is to say,the foundation of the group is the process of“mutual interaction and mutual ben-efit in resources”with Tang rulers.

在中国古代历史上,除了陆上丝绸之路、草原丝绸之路和海上丝绸之路外,还有一条自长安经吐谷浑到吐蕃,然后经尼泊尔到达印度,由此通往欧洲的第四条丝绸之路,即＂青藏高原丝绸之路＂。这条新的丝绸之路的形成虽是和亲、商贸、外交、文化、宗教和战争等多种力量的结果,但和亲的作用更为突出。隋唐与吐谷浑和亲开辟了自长安到青海的通道,吐谷浑、唐朝与吐蕃和亲开辟了自吐谷浑到拉萨的通道;吐蕃和亲圈不仅向西南延伸了这条丝绸之路,而且还拓展了通往中亚的路线。辽、西夏、回鹘、龟兹等政权与吐蕃和亲,又向东北、西北延伸了这条丝绸之路。蒙元与西藏萨伽款氏的联姻,进一步修复和巩固了这条丝绸之路。由此也可以将青藏高原丝绸之路称之为亲情之路。坐落在丝绸之路经济带上的我国西北各省区市,只要能够突出优势、彰显特色、打造品牌、借力发展,就能成为丝绸之路经济带上璀璨的明珠。

In the ancient history of China , besides the continental , prairie and maritime silk road , there was also the fourth silk road , i.e.“Tibetan Plateau Silk Road”, which started from Chang ’ an to Tugu-hun, Tubo, then to Nepal and India , and then to the Europe by the seaway .This new silk road was the result of combining forces like making peace with minority nationalities in the border by marriage , trade, religion and wars and so on , the first factor , however , played an important role .Sui and Tang dynasties ’ making peace with minority nationality Tuguhun in the border by marriage had opened the channel from Chang ’ an to Qinghai , and the marriage between Tuguhun , Tang dynasty and Tubo opened the channel from Tuguhun to Lhasa;marriage with Tubo not only expanded this silk road to the southeast , but also expanded the channel to the central Asia .The marriage between regimes like Liao , Xixia, Uighur, and Qiuci with Tubo then expanded this silk road to the northe
