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.
将生态系统服务的供给-需求关系纳入生态管理分区是一个热点问题。大多数研究都集中在生态系统服务的供给和需求之间的匹配关系上。然而，忽略了两者在不同匹配水平上的协调程度，即生态系统服务的供给和需求是否在高水平上趋于相互加强，或者在低水平上相互制约。因此，以大连市为例，本研究通过整合生态系统服务供给-需求的匹配和耦合协调关系，构建了生态管理分区的研究框架。研究发现，2005 年至 2019 年，大连市生态系统服务供给减少了 23.70%，需求增加了 22.54%。生态系统服务的供给和需求存在明显的不匹配和不协调，匹配和协调往往不能同时存在。利用叠加分析将大连市划分为生态保护、生态发展、生态改善和生态恢复四个生态管理区。本研究有助于将生态系统服务供给-需求的匹配和耦合协调关系纳入环境管理系统，对生态系统服务的可持续发展具有实际意义。
