RESUMO
Territorial ecological restoration planning is a carrier process for carrying out territorial space regulation and ecological restoration. However, current urban planning efforts only focus on ecological processes, and fail to coordinate the development of both ecology and society. Taking Shantou, a city in Guangdong Province, as an example, we focused on the identification of ecological restoration nodes and the development of differentiated planning strategies from a comprehensive ecological-social perspective. By considering ecosystem integrity, we extracted the ecological corridors and key points by identifying ecological sources and constructing resistance surfaces, constructed an ecological recreation service evaluation system from the social perspective in terms of recreational allocation and recreational value to identify key areas for recreation services, and obtained different types of ecological restoration strategies by synthesizing the results of ecology and recreation. The results showed that there were 136 ecological corridors and 77 ecological nodes in Shantou, with a total length of 380.58 km. The most important recreation areas were the coastline, several inland bays, and wetland tidal flats, with an area of 33.78 km2 and accounting for 1.6% of the total area. Low-level recreation areas was the largest, accounting for 57.3% of the total area. We proposed the composite strategy of "recreation expansion & fishery development", the connectivity strategy of "ecological construction & corridor connection", and the protection strategy of "vegetation restoration & development restriction". This study would provide a comprehensive analysis path for the ecological protection and restoration planning of coastal cities, and would help promote the practicality and maximizing the comprehensive benefits of territorial ecological restoration planning.
