摘　　要：房屋建筑是中国钢铁消费的主要领域,随着中国工业化进程的不断完善,钢铁作为用量最大的基础性原材料,大量投入到经济社会发展中。当前,中国房屋建筑中的钢铁存量已达很大规模,系统地摸清房屋建筑中的钢铁存量及生命周期,对未来废钢的合理利用具有指导意义。本文以长三角地区为例,利用动态物质流分析方法,测算建国以来该地区房屋建筑中钢铁存量的历史演变过程。结果显示:2016年长三角地区房屋建筑中钢铁总存量达677Mt,其中,江苏省46%、浙江省29%、安徽省16%、上海市9%。从单位面积钢铁存量看,上海市9 370kg/m^2、江苏省3 024kg/m^2、浙江省1 929kg/m^2、安徽省796kg/m^2。The construction industry is the main steel consumption field in China.As the most consumed basic raw material,steel has entered the economic and social development in large quantities.At present,the stock of steel in China’s building construction has reached a large scale.Systematic understanding of the steel stock and life cycle in building construction has guiding significance for the rational use of future scrap steel.This paper takes the Yangtze river delta as a case study and based on the dynamic material flow analysis,the paper also estimates the historical evolution of steel stocks in building construction in the region since 1949.The results show that in 2016,the total steel stock in building construction in the Yangtze river delta region reached 677 Mt,among them,Jiangsu 46%,Zhejiang 29%,Anhui 16%,Shanghai 9%.From the perspective of steel stock per unit area,Shanghai 9 370 kg/m^2,Jiangsu 3 024 kg/m^2,Zhejiang 1 929 kg/m^2,Anhui796 kg/m^2.
