摘要
利用邯郸市统计年鉴数据和实地调研资料,采用城市物质流分析框架研究邯郸市2005年物质流全景和1993─2005年物质输入和输出结构的时间序列变化.结果表明:13年间邯郸市地区生产总值增长3.4倍,物质输入增长1.1倍,物质生产力增长1.1倍,由1993年的151.8元/t上升至2005年的320.9元/t,反映了邯郸市前期经济发展与资源投入具有明显的"脱钩"现象;另一方面,邯郸市仍然遵循着"高投入、高排放"的发展模式,2005年物质净存量仅占全年物质通量的12.2%,大部分物质在开采当年并不进入经济系统而直接排放到生态系统中;同时,邯郸市经济发展的对外依存度逐年升高,从该市外调入的物质量所占比例由1993年的10.2%上升至2005年的39.2%,表明邯郸市经济发展将面临更大的资源压力.
Based on statistics data and field investigations, urban-wide material flow analysis （MFA） for Handan City is caiTied out to provide a full view of material flow in the city in 2005 and temporal variation of material input and output structure from 1993 to 2005. The results show that Handan economic development remarkably decoupled from material input in the last 13 years, with an increase of GDP by 340% and of material input by 110 % . CoiTespondingly, material productivity, an important indicator to show resources efficiency, increased from 151.8 Yuan/t of 1993 to 320.9 Yuan/t of 2005. However, the ＂mass production, mass consumption, mass discharge＂ development pattern still remains. The net-added-stock （NAS） of 2005 is only 12.2% , which means most of material was discarded into the nature without entering economic cycles. Meanwhile, Handan economic growth more and more depends on other regions, the ratio of input materials from other regions increased from 10.2% of 1993 to 39.2% of 2005.
