近些年来我国钢铁、铝等金属产量和消费量已经很高且快速增长，金属行业的能耗、物耗、污染物排放等都因此而过高，这不利于资源节约型、环境友好型社会的建设。为此，基于循环经济视角，分析了金属产品生命周期与循环经济的关联。在金属产品生命周期物质流分析模型的基础上，分析了我国钢铁工业2000－2012年的矿石资源、资源效率和废钢指数等情况，基于分析结果提出了相关的一些建议，为创建资源节约型的金属工业提供了一定的研究基础。

Volume of iron and steel, aluminum etc metal production and consumption are extremely high and in a rapid increment in China in recent years, the energy use,materials consumption and waste emission of metal industry are excessively high correspondingly, which is not conducive to con-struct a resource-saving and environment-friendly society.Based on the perspective of circular e-conomy,the relationships between metal manufacturing process and circular economy , metal products life cycle and circular economy analyzed.The iron ore index, iron resource efficiency and steel scrap index of China’ s iron and steel industry during the period 2000-2012 were investigated by the metal products life cycle substance flow analysis model.Some suggestions were put forward based on the ana-lyzing results.The contents provided some basis for the constructing of a resource-saving metal indus-try.
