| Abstract: | Research on spatial flow as it relates to the relationship between the supply and demand of ecosystem services supports a significant connection between the supply of ecosystem services and human well-being. Understanding the entire process of the production and flow, as well as the use of ecosystem services, accurately assessing the balance of supply and demand of ecosystem services, and establishing a two-way feedback relationship between supply and demand are vital for the scientific management of the ecosystem and ensuring the sustainable development of regional resources. Based on a large number of relevant publications, this paper comprehensively summarizes the concepts and assessment methods of ecosystem service supply and demand from the perspective of ecosystem service supply and demand, and discusses the impacts of land use and climate change on the temporal and spatial changes of ecosystem services under the background of global change. Then, an analysis of the research progress in the ecosystem services spatial flow indicated that there are still deficiencies in the quantification of cultural services, the dynamics of ecosystem service flow and the driving mechanism of ecosystem services. We also propose that clarifying the driving mechanism and transfer process of ecosystem services, and realizing the mutual conversion between different spatial-temporal scales of ecosystem services, is an important approach for improving the application of ecosystem services research in practice in the future. |
