Body
The difficulty of unequal distribution of rights, responsibilities and interests between the supply and demand sides of ecosystem services is a key issue that hinders the agreement of ecological compensation. This study expects to identify the key elements of regional ecological compensation by identifying the categories, flows and directions of ecosystem service flows, and providing the essential supporting basis for the adjustment of stakeholders' rights, responsibilities and interests. Therefore, clarifying the flow model of ecosystem services in the region and developing an ecological compensation scheme for both supply and demand of ecosystem services are the research questions of the article. To address the above questions, this study utilizes a new perspective of ecosystem service flow to determine the transmission paths and flows of ecosystem service values by comprehensively considering the spatial and temporal states of ecosystem service flows, and uses this to form the content, scope and criteria of ecological compensation. Taking Dongying city as an example, this study analyzes the flow direction and supply and demand levels of ecosystem service flows in the Yellow River Delta with multiple sources of data, including satellite remote sensing, real-time monitoring and statistical yearbooks, and determines the ecological compensation mechanism in Dongying city on this basis. The study shows that: (i) the supply of ecosystem services in Dongying mainly comes from the water ecosystem within the Yellow River Delta; (ii) the ecosystem service flow integrates the potential supply of ecosystem services and can present the flow pattern of ecosystem services, and the formulated ecological compensation scheme can provide sufficient and multi-source compensation funds for the Yellow River Delta. The research results provide a theoretical basis for the application of ecosystem service flow theory in ecological compensation, which contributes to the construction of a regional ecological compensation mechanism with clear rights, responsibilities and interests, and promotes the ecological restoration and sustainable development of the region.
