国内灰绿基础设施协同策略研究进展及展望

从构建城市生命支持系统的视角，重新认知灰色与绿色基础设施以及灰绿协同的重要性。通过系统梳理国内相关研究，总结灰绿协同在涉水基础设施、交通基础设施、能源基础设施三个热点方向上的研究进展，继而提出灰绿协同的概念、内涵、特征及理论框架，为后续细化的协同技术体系提供理论支撑和现实依据。此外，探讨灰绿协同理论在过往研究中的局限，并在长期视角下针对协同方向、协同技术、协同评价、协同数字化提出四点展望，为强化基础设施协同，扎实推进生态文明建设提供相应建议。

Research Progress and Prospect of Domestic Gray-green Infrastructure Collaboration Strategy

From the perspective of building the urban life support system, the importance of grey and green infrastructure as well as grey-green collaboration is re-cognized. The research progress of grey-green collaboration in the three hot directions of water-related infrastructure, transportation infrastructure and energy infrastructure by systematically sorting out the relevant domestic studies, and then the concept, connotation, characteristics and theoretical framework of grey-green collaboration are proposed, which will provide the theoretical support and practical basis for the subsequent refinement of the collaborative technology system. In addition, the limitations of the grey-green collaborative theory in the past research are discussed. And four-point prospects are proposed for the collaborative direction, collaborative technology, collaborative evaluation and collaborative digitalisation, which provide the corresponding suggestions for strengthening the infrastructure collaboration and solidly promoting the construction of ecological civilization.
