摘要：Copper in-use stocks play an important role in copper cycle. Investigating copper in-use stocks is essential to realize more efficient and sustainable utilization of copper resources. A systematic analysis at the sub-national level is still inadequate, especially for those sub-regions of the studied area. In order to fill the research gap, this study uses Chinads Sichuan Province as a case to assess copper in-use stock and its spatial distribution at the sub national level in China. Employing a bottom-up modelling approach, this study calculates the copper in-use stocks in Sichuan and its 21 prefectural sub-regions in 2014. Our results show that, 1) copper in-use stocks of the whole province were 1,891 Gg and the amount of in-use stocks per capita was 231%, which is far below the level of the developed countries and implies significant growth potential in the future. 2) Among all the categories calculated, residential buildings, non-residential buildings, automobiles, air conditioners, power substations, refrigerators, power transmission and distribution cables were the main reservoirs of copper and collectively took nearly 80% of the total stocks. Stocks per capita for the prefectural sub-regions in Sichuan are relatively close, ranged from 17.1 to 28.8 kg. 3) Distinction between rural and urban copper in-use stocks indicates Sichuanos rural copper stocks occupy an indispensable proportion. 4) The stocks density for prefectural regions varied from 149 kg/km(2) to 34,302 kg/km(2), indicating significant imbalance of spatial distribution characteristic and an unignorable intra-provincial disparity.
