“…Moreover, Dalian is a famous coastal tourist city in China, which has developed tourism and attracted many tourists from all over the world. However, economic and population growth and extensive food production methods have contributed to land degradation and CO 2 emission in Dalian (Du et al 2019). Considering the above reasons, we selected six key ESs: food supply (FS), carbon sequestration and oxygen release (CSOR), water retention (WR), soil conservation (SC), habitat support (HS), and landscape aesthetic (LA).…”

Integrating ecosystem services supply-demand relationships into ecological management zoning is a hot topic. Most studies have focused on the matching relationship between the supply and demand of ecosystem services. However, the extent to which both are coordinated at different matching levels is ignored, that is, whether ecosystem services supply and demand tend to reinforce each other at high levels or constrain each other at low levels. Therefore, taking Dalian as an example, this study constructed a research framework for ecological management zoning by integrating the matching and coupling coordination relationship of ecosystem services supply-demand. We found that the supply of ecosystem services in Dalian decreased by 23.70% and the demand increased by 22.54% from 2005 to 2019. There was an obvious mismatch and disharmony in the supply and demand of ecosystem services, and the matching and coordination often did not exist simultaneously. Overlay analysis was used to divide Dalian into four ecological management zones: eco-conservation, eco-development, eco-improvement, and eco-restoration zones. This study helped in integrating the matching and coupling coordination relationship of ecosystem services supply-demand into the environmental management system, which has practical significance for the sustainable development of ecosystem services.
