This paper presents compositional analyses and structure observations of unearthed Shang Zhou dynasty bronze relict samples and environmental conditions of the sites where the samples were collected.Research results revealed that the bronze relics had been continuously corroded with time.The corrosion layer consisted of at least two sub layers ,such as oxide and carbonate.There was a mechani‐cal corrosion sub layer found in few samples (a loose sub layer) . A SnO2 sub layer also occurred in a few samples. The thickness of bronze corrosion layers varied with the different climate environments in which the samples were taken. Their thickness was 50~260μm and 320~800μm and humid climate re‐gions respectively. In the view of natural corrosion resistance , bronze is recommendable as a material for HLW repository system canisters.%文章论述了出土商周时代青铜文物的化学成分和结构特征以及样品采集地区的环境条件。研究表明青铜文物随时间而不断腐蚀。腐蚀层至少由两个亚层组成，即氧化物层和碳酸盐亚层。有些样品出现物理腐蚀亚层，即疏松层；有些样品则产出SnO2亚层。青铜腐蚀层的厚度在不同环境条件下发生变化，干旱条件下为50～260μm ，潮湿条件下为320～800μm。从天然抗腐蚀观点看，青铜可推荐作为高放废物处置系统废物罐的材料。
