Abstract: Grey-green infrastructure provides vital public space resources for island villages. Currently, research on their integration primarily focuses on ecological and low-carbon aspects. In the context of inventory planning and urban-rural integration, exploring the potential for integrating grey-green infrastructure resources to promote the integration of ecology, production, and livelihoods (the 'Three Livelihoods') is essential for the revitalization and common prosperity of island villages. Based on an analysis of the types and elements of grey-green infrastructure and the 'Three Livelihoods' spaces in island villages, this paper uncovers the coupling mechanism between them and proposes a planning strategy where grey-green infrastructure integration drives the 'Three Livelihoods Integration'. This includes fostering the integration of nature and humanity in ecological spaces, the integration of agriculture and tourism in production spaces, and the integration of culture and tourism in living spaces. Taking Daidong Town, Zhoushan, Zhejiang Province, as an empirical case, this paper starts with the foundation and challenges of the area's development. Through technical methods such as the identification of grey-green integration elements, planning guidance and control, and goal construction, it provides theoretical and practical foundations for the comprehensive revitalization and sustainable development of island villages.
