上海市物质流分析

Material Flow Analysis of Shanghai City

利用物质流的理论和方法,依据欧盟导则,分析了1990-2003年间上海市经济系统的物质总需求、物质消耗强度和物质生产力等主要指标,并且同国家物质流账户以及国外的城市进行了比较。研究结果表明:上海市巨大的物质总需求和直接物质消耗给上海市的生态环境带来了巨大的压力;上海市的物质消耗强度远远大于全国平均水平;上海市的物质生产力水平与发达国家还有一定的差距。利用情景分析法,提出上海未来的循环经济发展战略。

The material flow theory and methodology based on the Eurostat guidelines have been applied to analyze quantitative characteristics of the total material requirement （TMR）, the material intensity and the material productivity in the city of Shanghai from 1990 to 2003. The conclusions reveal that the big total material requirement and direct material input brings huge pressure on the envi- ronment on the city of Shanghai. At the same time the efficiency of the resource utilization in Shanghai is lower than developed country. Taking the present material productivity of shanghai as the start point ,we propose a mid and long term strategic goal in connection with the four - fold and the ten - fold increase in resource efficiency for 2025 and 2050 , respectively.
