一种分析城市代谢系统互动关系的方法

A method of analyzing the interactions in an urban metabolism system

提出一种集成了能值分析和生态网络分析,研究城市代谢系统组分间互动关系的方法.基于城市复合生态系统和城市代谢的基本原理,在确定城市系统代谢单元和代谢环节的基础上,采用提出的方法,分析了城市代谢单元之间掠夺、限制和共生的关系.最后,以中国北京、上海、天津、重庆、广州和深圳6大城市为例进行了实证研究.结果表明,天津、重庆、广州市社会经济子系统对自然生态子系统存在着掠夺关系;北京、上海和深圳市自然生态子系统对社会经济子系统存在着限制关系;实现城市代谢系统良性运行的前提在于调控代谢单元间的互动关系,促进城市代谢单元间的协调共生.

We integrated energy analysis with eco-network analysis to develop a method for use in analyzing the interactions in an urban metabolic system. Based on the principles of an urban complex ecosystem and urban metabolism, we determined the metabolic units and links, and then investigated the interactions of the urban metabolism system, including exploitation, control, and mutualism, by the suggested method. Finally, the integrated analysis method was employed to study the metabolic systems of Beijing, Shanghai, Guangzhou, Tianjin, Chongqing, and Shenzhen. The results showed that the socioeconomic subsystems of Tianjin, Chongqing, and Guangzhou exploited the natural ecological subsystems, while the natural ecological subsystems of Beijing, Shanghai and Shenzhen controlled the socioeconomic subsystems. For sustainable operation of urban metabolic processes, it is essential to regulate and control the relationships between urban metabolic units to improve their mutualism.
