摘要： 给出了金属物质社会蓄积量的分析方法.分析了在金属消费量保持不变、线性变化及指数变化3种情况下,金属消费量对金属物质社会蓄积量及其回收率的影响.计算得到了我国2006～2009年期间铝的社会蓄积量变化情况:在此期间,铝社会蓄积量增长很快,2009年时达到了8 890万t;铝社会蓄积量回收率的均值为1.45%;随着未来我国铝消费量增速的降低,铝社会蓄积量回收率会逐步提高.对金属物质的社会蓄积量分析,可以为金属工业的资源战略、产业政策和环境政策的制定提供一定依据.

关键词: 铝, 消费量, 社会蓄积量, 平均使用寿命, 回收率

Abstract: Social stocks of metallic substance mainly refer to in-use metal stocks. Analytic method of the in-use metal stocks was given. Influences of metal consumption on the in-use metal stocks and its recycling rate were analyzed under the three circumstances: the metal consumption remains unchanged, chang in a linear trend and change in an exponential trend. In-use aluminium stocks for China were calculated during the period 2006~2009. The results revealed that in-use Al stocks keep increasing and reach 88.9 millions tons in 2009, its average recycling rate is 1.45 percent. Recycling rate of in-use Al stocks will rise in the future along with the reduction of the increasing rate of aluminum consumption. Analysis of in-use metal stocks can provide some basis for resource strategy, industrial policy and environmental policy-making of China's metal industry.
