摘要： 城市生态系统内部各组分之间存在着错综复杂的关系,任一组分的变化会对其他组分产生不同程度的影响.快速的城市化进程带来了一系列影响城市可持续发展的问题.若想从根本上消除这些可持续发展隐患,需要采用“耦合”方法.本文明晰了“耦合”的3种应用情景及相应定义表述,同时对城市耦合理论发展脉络进行梳理,分别从物理耦合视角及政策效果耦合视角进行能-水-食物-土地-气候变化(EWFLC)五系统两两分析总结.从物理耦合视角解读发现,目前的耦合研究大多集中在城市尺度,并且主要针对两个系统之间的直接耦合关系,间接耦合关系研究相对缺乏,两系统的关联多会对社会和经济产生积极影响.从政策效果耦合视角来看,目前针对五系统的政策多面向直接解决目标系统问题,政策实施的中间目标大多可量化,且政策效果评估大多含有多个指标.在此基础上,本文提出了可同时结合物理耦合及政策效益耦合的城市EWFLC五系统分析框架,旨在帮助城市开展政策遴选,实现城市可持续发展.

Abstract: Intricate associations exist between the internal elements of urban ecosystems, with the adjustment in one element can exert impacts of varying degrees on others. The rapid urbanization has brought numerous challenges on the urban sustainable development. To basically solve these problems, the “nexus” approach needs to be adopted. We clarified three application scenarios of “nexus” and their corresponding definitions. Meanwhile, the development of urban nexus theory was also provided. The analysis between any two characters among energy, water, food, land and climate change (EWFLC) systems was presented from the perspective of the physical nexus and policy effect nexus, respectively. From the perspective of the physical nexus, most the present stu-dies are concentrated on the urban scale, and aim at the direct nexus, lacking of indirect nexus reaches relatively. Most of the relationships between each two characters will have positive impacts on the society or economy. From the perspective of the policy effect nexus, current policies focused on the five systems are mostly oriented to directly solve problems of targeted system. The intermediate objectives of policy implementation are mostly quantifiable. There are generally multiple indicators of the policy effect evaluations. Furthermore, an analysis framework of urban EWFLC systems simultaneously combining physical and policy nexus was proposed in this study, which aimed to help make policy selections and realize urban sustainable development.
