中文摘要：

城市代谢是适应当前全球环境问题研究需要而出现的理论研究,与国家制定的环境管理目标具有内在一致性.本文对城市代谢概念进行解析,并指出城市代谢物质实体研究的意义;概述了城市代谢研究的主要方法并进行优缺点比较;解读了城市代谢物质实体空间研究的系统边界、内涵和研究方法等;总结城市物质实体空间代谢的应用研究进展,提出城市代谢研究存在概念体系、基础理论体系、交叉学科综合理论体系不完善,导致研究发展速度难以满足当前发展的需要、典型案例研究数量有限的不足;建议未来研究可加强在国家间进行实证研究案例的综合比较,以及城市生态系统演化规律、典型城市代谢的优化模式和以实体城市为基本研究单元的环境管理决策支持系统研究.

英文摘要：

Urban metabolism is a basic theory for coping with global environmental problems, which is coherent with the aims of national environmental management. This paper analyzed the concept of urban metabolism, and pointed out the meaning for urban metabolism in physical space entities; re- viewed the current methods for urban metabolism and its merits and shortages; analyzed the system boundaries, connotation, and methodologies; and summarized the advances on urban meta-bolism practices in physical space entities. At last, we made conclusions that there were shortages, inclu- ding conception system, basic theory system, and interdisciplinary integrated theory system in cur- rent urban metabolism research, and the current eases studied in urban metabolism were limited and not suitable to the harmony development between society, economy, and environment. In the fu- ture, we need to strengthen comparison between different case studies from different countries, de- velop the prior modes of typical urban metabolism research, identify the mechanism for urban ecosystem, and strengthen the spatial decision support system of environmental management taking urban spatial entity spaces as units.
