The ecosystem services approach provides an efficient way to support urban green infrastructure planning. Such an assessment, together with mapping, can effectively produce spatial analyses on a specific scale, helping to maintain multi-functional landscapes and plan urban green infrastructure. In turn, green infrastructure can offer a wide variety of ecosystem services, promoting landscape sustainability. This study develops a methodology for the planning of urban green infrastructure based on an ecosystem services approach that assesses the supply capacity of ecosystem services, and identifies possible spatial characteristic areas for interlinking urban green infrastructure within the study area. More specifically, from a landscape perspective, we use 32 ecosystem services (as X-axis) and different land use types (as Y-axis) to build an ecosystem service assessment matrix. We then take the municipality of Barcelona as an example, using the latter to assess and map ecosystem services within the city through ArcGIS, which shows the spatial distribution characteristics of ecosystem services provision. We identify possible spatial areas - which include ecosystem services provision, barren, and obstructed areas - by overlapping the ecosystem services assessment maps. Ultimately, the results provide a reference for urban green infrastructure planning by recognizing priority protected areas, new construction areas, potential areas, and renewal areas. •Using the ecosystem services assessment matrix to assess the ecosystem services supply and visualize the results by ArcGIS.•To guide urban green infrastructure planning by identifying the possible spatial characteristic areas in the study area.•To provide a theoretical framework of urban green infrastructure planning based on ecosystem services.
