Urban green corridor construction considering daily life circles: A case study of Wuhan city, China

Urban green corridors are the vital link connecting urban blue-green space and provide ecosystem services. Although numerous studies have been carried out to identify urban green corridors, few studies have focused on the demand of both urban residents and species for blue-green space from the perspective of daily life circles, which are the basic unit of requirements in city area. In this study, we proposed an improved method that considered three types of daily life circles and further integrated the socioeconomic factors in daily life circles that affect the stability of green spaces into the construction of green corridors. We adopted the city central area of Wuhan as a case study to apply the evaluation method. The results indicated that the three types of daily life circles were close to the practical life. Socioeconomic factors in the daily life circles affected the stability of blue-green space; thus, it is necessary to integrate them into the green corridor construction. Accordingly, we improved a strategy to construct green corridors based on daily life circle theory. Our method extends the green corridor construction methodology, and the research results can provide a significant reference for urban planning to build more reasonable green corridors to move toward both biodiversity and satisfy the demand of residents and species for blue-green space.
