| 摘 要： | 1972年出版的Romacrab的“增长的极限”报告预测地球矿产资源的需求量不久将超过供给能力，进而导致现代文明的终结。几十年过去了，其预测的情况并未出现。究其原因，材料的再生循环功不可没。因而在评价资源寿命时必须考虑再生循环的影响。本文提出了材料再生循环指标的概念，并利用材料再生循环指标对金属资源寿命重新进行评估。

| Abstract: | In the report of THE LIMITS TO GROWS published by Romacrab in1972,it is predicted that the requirement of mineral resources on earth would exceed serviceability,which would lead to the end of modern cibilization.But thirty years has past,the prediction don't come tru e.The material recirculation palys an important role.So when we appraise the resource life,the recirculation factor must be considered.The material recirculation index is brought into this article to be used for reappraisal of the metal resource life. |
