摘要
基于欧盟的物质流分析(MFA)框架,对青岛市城阳区的物质代谢状态和代谢强度进行了系统分析.结果表明:1995─2004年城阳区资源投入量和污染物排放量分别增长3.6和1.8倍,化石燃料和矿物约占资源投入量的50.26%~76.30%,进口资源量所占比例呈逐年增长趋势,经济发展的资源外部依赖性较强.万元GDP资源投入由6.01 t降至3.56 t,万元GDP污染物排放量也降低了63.74%,表明城阳区经济发展的资源利用效率和生态效率已有不同程度的提高,但仍远高于发达国家20世纪末期的水平,因此提高资源生产力和控制污染物排放是实现城阳区可持续发展的必由之路.
Base on the framework of material flow analysis （MFA） proposed by Eurostat, material metabolic state and metabolic intensity for the Chengyang District in Qingdao were analyzed. The results indicate that resources input and pollutant output increased by 3.6 and 1.8 times respectively from 1995 to 2004. Fossil and mineral contributed to about 50.26% - 76.30% of resources input. Contributor of imports to re^urces input represented obvious increasing trend, which shows that local economic development depends on external resources. Resources input per ten thousand Yuan GDP decreased to 3.56 t from 6.01 t, and pollutant output per ten thousand Yuan GDP decreased by 63.74%, which indicates that resources utilization efficiency and eco-efficiency of local economic development has been enhanced in different extent. However, compared to the developed counties in the end of last century, resources utilization efficiency and eco-efficiency are still very low. Therefore, in order to promote the sustainable development of Chengyang District, it is essential to improve the utilization efficiency of natural resources and control pollutant output.
