【摘要】 运用物质流分析(Material Flow Analysis,MFA)方法,并在欧盟MFA指标体系的基础上增加了资源循环利用新指标,收集并分析了1995-2005年中国经济系统的物质投入和环境影响的2000多个数据,得到1995-2005年中国直接物质投入量与物质投入结构、国内物质输出量与污染排放结构、物质流强度的变化。结果表明:十年来中国直接物质投入量与国内物质输出量增长均随GDP增长呈线性增长趋势;由于直接物质投入量的资源投入结构发生的巨大变化,导致工业固体废弃物的排放量不断增长;资源生产率出现低位下降;2005年中国资源循环利用率首次突破5%,但总体水平仍然低下。最后在计算结果基础上,指出MFA方法存在的不足之处。更多还原

【Abstract】 The amount and structure of direct material input(DMI) and domestic processed output(DPO) in China from the period 1995 to 2005 are analyzed by the derived indicators of material flow analysis(MFA) on the basis of more than 2000 items of data on material input and environmental impact at the national level.In addition to traditional MFA indicators,the ration of recycled material(RRM) is added as the new indicator.According to the research,it is a linear development between GDP and the derived indicators of DMI and DPO.The great change of material input causes the continuous increase of industrial solid waste emission.The RRM in China in 2005 exceeded 5% for the first time but it was still very low.Finally some weaknesses of MFA are pointed out on the basis of calculated results.更多还原
