CHANGES OF SORUCE OF EARLY CHINESE BRONZE

青铜器的物源研究对于了解历史青铜器文化的发展，已成为考古科学中更为重要的信息。从东亚文化发展的角度，获得了中国早期及邻近地区青铜器的化学成分和铅同位素比值。样本来自东京国立博物馆、森奥库博物馆、香港中文大学、新疆考古研究所等。在这项工作中测量了200多个样品的铅同位素比率。样本地点分布在中国西北部的新疆省、西南部的云南和四团省到韩国和日本。韩国和日本的青铜器样本作为与日本青铜器文化起源的关系被纳入了这项工作。除了这些样本外，越南和南部沿海的样本被纳入中国南部的样本。结果表明：1)西周前期，含铅特殊的四团青铜似乎并没有被带到长江中游地区。2)新疆的青铜器技术是在两千多年的时间里独立于中原文化发展起来的。3)南方沿海地区的青铜器似乎没有受到长江青铜的影响。4)韩国和日本受到中国青铜文化的强烈影响。但是，在引进青铜搬运技术后，韩国的矿山在短时间内得到了发展。

For the understanding of historical bronze culture development, the provenance study of bronze objects became more important information in archaeological science. Chemical composition and lead isotope ratios of bronze objects of early China and near the area were obtained from the viewpoint of East Asian cultural development.Samples were obtained from Tokyo National Museum, Sen'oku Museum, Chinese University of Hong-Kong, Xinjiang Archaeological Institute and others. More than 200 samples of lead isotope ratios were measured in this work. The sample locations were distributed from Xinjiang province in the northwestern part of China and Yunnan and Situan provinces in the southwestern part of China to Korea and Japan. Korean and Japanese bronze samples were included in this work as the relationship to the beginning of Japanese bronze culture.In addition to these samples, Vietnam and southern coastal samples were included as the samples of southern part of China. Several topics obtained were summarized as follows : 1) In early Western Zhou period, Situan bronze contained special lead seems to be not brought to middle streams of Yangze river area. 2) Bronze technique in Xinjian was developed independently from the central China culture during the 2 thousands millennium. 3) It seems that the bronze objects in southern coastal area did not have the influence of the Yangze river bronze. 4) Korea and Japan received strong effect of Chinese bronze culture. However after the bronze handling technique was introduced in Korea, Korean mines were developed in a short period.
