金属的社会蓄积量在一定程度上决定可供回收的二次资源的数量.给出了金属社会蓄积量的分析方法:Top-down分析方法.分析金属消费类型(消费量保持不变、消费量指数变化和消费量线性变化)对金属社会蓄积量、可回收率和平均年龄的影响.在此基础上,对我国2006-2009年间铝、铜的社会蓄积量进行了分析,得到以下分析结果:此期间内铝、铜社会蓄积量快速增长,2009年时分别达到了8890万t和5140万t,平均可回收率分别为1.45％和0.30％,平均年龄分别为4.65 a和6.89 a.随着未来我国铝、铜消费量增速的降低,铝、铜社会蓄积量的可回收率和平均年龄将会有所上升.
金屬的社會蓄積量在一定程度上決定可供迴收的二次資源的數量.給齣瞭金屬社會蓄積量的分析方法:Top-down分析方法.分析金屬消費類型(消費量保持不變、消費量指數變化和消費量線性變化)對金屬社會蓄積量、可迴收率和平均年齡的影響.在此基礎上,對我國2006-2009年間鋁、銅的社會蓄積量進行瞭分析,得到以下分析結果:此期間內鋁、銅社會蓄積量快速增長,2009年時分彆達到瞭8890萬t和5140萬t,平均可迴收率分彆為1.45％和0.30％,平均年齡分彆為4.65 a和6.89 a.隨著未來我國鋁、銅消費量增速的降低,鋁、銅社會蓄積量的可迴收率和平均年齡將會有所上升.

Social stock for metal determines secondary or recoverable resources to a certain extent.Top-down analysis method for the studying of metal in social stock was given.Influences of metal consumption under three circumstances,that is keeping constant,varying in a linear trend and in an exponential trend,on one kind of metal's social stock,recyclable ratio and average age were analyzed.Al-contents and Cu-contents in social stock for China during the period 2006-2009 were calculated.The results reveal that Al-contents and Cu-contents in social stock kept increasing and reached 88.9 million tons and 51.4 millions tons in 2009,respectively,their average recyclable ratios are 1.45％ and 0.30％,and the average ages are 4.65 years and 6.89 years,respectively.The recyclable ratios and average ages of Al-contents and Cu-contents in social stock will rise in future along with the decline of the increasing rate of aluminum consumption and copper consumption.
