城市经济系统的物质存量和流量研究,有助于制定合理的资源战略、产业政策和环境政策。本文以邯郸市行政区为系统边界,采用自下而上方法对邯郸市截至2005年底的钢铁和铝的存量进行了调查研究,给出了钢铁和铝的使用规模和强度,计算了邯郸市钢铁和铝的总存量及其分布情况,并与北京和美国New Haven市的钢铁存量进行了对比分析。结果表明:截至2005年底,邯郸市使用中的钢铁存量为1333kg/人,约为北京的1/2,美国NewHaven市的1/7,最大存量来自于建筑,占总存量的66.6%,其次是基础设施和和交通系统,分别占19.7%和7.9%;铝存量为19.6kg/人,其中建筑铝存量占61.5%,基础设施存量为4.1%,交通系统存量为24.4%;铝的人均存量约为钢铁的1/68。
The research on the material stock and flow of urban economic system helps to formulate a reasonable resource strategy, industrial policy and environmental policy. In this paper, Handan city as a system boundary, using a bottom-up approach to Handan City as of the end of 2005 to investigate the stock of steel and aluminum, given the use of steel and aluminum scale and intensity, calculated Handan Iron and Steel and The total stock of aluminum and its distribution were compared with the steel stock in New Haven, Beijing and the United States. The results show that by the end of 2005, the stock of steel used in Handan City was 1333kg / person, about 1/2 of that in Beijing and 1/7 of New Haven in the United States, with the largest stock being from construction accounting for 66.6% of the total stock, followed by Infrastructure and transportation systems, accounting for 19.7% and 7.9% of the total respectively. The aluminum stock is 19.6kg / person, of which 61.5% is for construction aluminum, 4.1% for infrastructure and 24.4% for transportation. The per capita inventory of aluminum 1/68 for steel.
