摘　　要：“无废城市”建设试点的提出标志着中国“无废社会”战略的实施和落实。采用物质流分析法量化了盘锦市2005—2018年的城市物质代谢;采用层次分析法和熵权法综合评价城市经济、资源、环境子系统的发展水平;借助系统动力学探究“无废城市”综合管理相较于其他发展模式对城市代谢系统优化的多方面潜力。结果表明:盘锦市物质投入产出具有“高投入、高排放、高隐藏流”特点;资源效益发展受限影响着整体城市代谢水平;在“无废城市”综合管理模式下,预计2025年资源产出率将在2018年基础上提高20.29%,环境效率提升4倍,极大地促进城市代谢系统资源、环境、经济层面的优化。The proposal of“zero-waste city”construction pilot symbolizes the implementation of the“zero-waste society”strategy in China.In this study,material flow analysis was used to quantify urban material metabolism in Panjin from 2005 to 2018.The comprehensive evaluation of the analytic hierarchy process and entropy weight method was adopted to evaluate the development level of the urban economy,resources,and environmental subsystems.Using system dynamics,this paper explored the potential of“zero-waste city”comprehensive management to optimize urban metabolic systems compared with other development modes.The results showed that the material input-output of Panjin had the characteristics of high input,high emission,and high hidden flow.The limited development of resource efficiency affected the overall level of urban metabolism.Under the comprehensive management mode of“zero-waste city”,it was expected to increase resource productivity by 20.29%and environmental efficiency by four times by 2025,based on 2018,greatly promoting the optimization of resources,environment,and economy of the urban metabolic system.
