一、引言城洋铜器群发现于陕西省西南的汉中盆地东部,秦岭、巴山耸立于南北两侧,中部有汉水由西向东流过。上世纪50年代以来,汉中东部渭水与汉江交汇处附近的城固、洋县两县,不断有商代青铜器出土数量较大,种类丰富,既有典型中原风格的青铜礼容器,又有很多地方特征明显的青铜器类,如兵器、弯形器、璋形器等。很多学者撰文对其年代、类型、来源以及文化归属等诸多问题进行了深入的研究。在年代学方面,根据学者们对城洋青铜器年代上下限的考证,参考相关的测年数据,可以看出绝大部分商代青铜器的绝对年代范围当在公元前15世纪至公元前11世纪。 I. INTRODUCTION The Chengyang Bronze Group was found in the east of the Hanzhong Basin in the southwest of Shaanxi Province. The Qinling Mountains and Bashan Mountain stand on both sides of the north and south. Hansen water flows from west to east in the middle.

There are also many places Characteristics of the bronze category, such as weapons, crooked, Zhang-shaped device.

In terms of chronology, according to the textual research on the upper and lower limits of the Chengyang bronze ware by scholars, with reference to the relevant dating data, it can be seen that the absolute age of most Shang bronzes ranged from the 15th century BC to the 11th century BC.
