Blue-Green Space

Blue-green space, as a common terminology in the field of territorial and spatial planning, refers to the open space with nature as the main body in urban areas. It includes the blue space of surface water bodies, such as rivers, lakes, and wetlands, and the green space of green systems, such as greenways, forests, and parks. It not only carries the functions of ecological protection and environmental beautification, but also provides necessary places for residents’ social and physical activities, which is an important guarantee for improving residents’ well-being and building a healthy and resilient city.
