生态系统服务供需关系及空间流动研究进展（英文）

基于生态系统服务供需关系的空间流动研究是连接生态系统服务供给与人类福祉的关键环节。理解生态系统服务产生、流动、使用的全部过程，准确评估生态系统服务供需平衡状况，建立供给与需求之间双向反馈关系，对于科学管理生态系统和保障区域资源可持续发展具有重要意义。综合大量相关文献，本文从生态系统服务供需关系角度出发，归纳了生态系统服务供给、需求的概念和评估方法，阐述了全球变化背景下，土地利用和气候变化两个主要驱动力对生态系统服务时空变化的影响。系统梳理了生态系统服务空间流动方面的研究进展，发现目前研究在文化服务的量化、生态系统服务流动动态研究以及生态系统服务的驱动机制研究方面存在不足，提出明确生态系统服务驱动机制和转移过程、实现生态系统服务不同时空尺度之间的相互转换，是未来将生态系统服务研究更好地用于实践的重要方法。

A Review on the Supply-Demand Relationship and Spatial Flows of Ecosystem Services

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.
