中文摘要：

欧亚大陆在古代最著名的交往通道是西汉建立的丝绸之路，在这之前有金属之路。金属之路位于更北的草原地带，始于金属时代，并被丝绸之路所取代。金属之路体现了东西方的碰撞与交融，不同时期有不同的文化格局。在公元前1千纪初，欧亚草原地区人群在技术、社会结构和意识形态上都发生了重大的改变。大多数学者把这种大范围巨大变革的原因归结于游牧社会的兴起。

英文摘要：

When we analyze the cultural remains in the steppe at the initial stage of the nomadic societies in the early 1st Millennium BC, we can find that they are mainly distributed on the north bank of the Black Sea, the Kuban River Valley, southern Siberia, Mongolian Plateau and the southeastern Inner Mongolia of China. This paper discusses the interaction among these cultures through the comparisons of the Upper Xiajiadian Culture in southeastern Inner Mongolia and other steppe cultures. The research reflects that from the formation of the Upper Xiajiadian Cnlture in early and mid Western Zhou Dynasty, there was interaction between this culture and the Slab Grave Culture in Mongolian Plateau. During the prosperous period of the Upper Xiajiadian Culture, this interaction was still remained, while the phenomena of synchronous development were shown in the Upper Xiajiadian Culture and the Arzhan Tombs of Tuva in the southern Siberia, indicating the expanding of the scope of this cultural interaction. The curved animal motif discovered widely in the Eurasian Steppe represented the synchronization of the Steppe Metal Route going through the Eurasian Steppe.
