Spatial accessibility between commercial and ecological spaces: A case study in Beijing, China

Abstract

Abstract The accessibility evaluation between ecological and commercial spaces is important for “production-living-ecological” coordination. This article selects Tongzhou of Beijing as an example. Significance tests showed the commercial facilities in Tongzhou district followed an agglomerated distribution. Further exploration of the relationship between concentrated commercial and ecological spaces show the distribution of ecological space in Tongzhou district is unbalanced, which shows that the northern, western, and central regions of Tongzhou district cover a wide area, whereas the southeast region has a low level of accessibility. The coverage rate of ecological space of each street with 10 min walking is lower than 50% on average. The coverage rate of walking for 20 min varies greatly, and the sub-districts with high coverage rate are basically distributed along the north–south central axis and east–west central axis. Emerging commercial spaces have poor accessibility towards ecological space, which indicates that in the new commercial space, ecological space has not been considered in the planning. It also reflects that in the existing daily ecological management, managers tend to focus on the ecological remediation of the built area and ignore the ecological planning in the community construction stage of commercial space.
