Investigating the interlinkages between the water-energy-food nexus (WEF-Nexus) and ecosystem services has emerged as a significant and trending topic worldwide. Drawing on the conceptual understanding of the WEF-Nexus,ecosystem services,and their interplay,this paper reviews the research advancements in the nexus's coupling with ecosystem services across three dimensions: relationship,system,and management. The paper then investigated the deficiencies of the current research on the coupling between the WEF-Nexus and ecosystem services,and discussed the future prospects. The results showed that the current coupling research mainly focused on analyzing the interactions and supply-demand dynamics between the WEF-Nexus and ecosystem services,developing and assessing water-energy-food-ecology coupling systems,and introducing novel concepts and management strategies for these systems. However,the current research on the coupling between the WEF-Nexus and ecosystem services remains in its nascent phase. There is a lack of theoretical system and technical approaches to reveal the interactive coupling relationship and action mechanism between the WEF-Nexus and ecosystem services. The establishment and mechanism analysis of the WEF-Nexus-ecosystem services coupling system are lacking,and the practical application of this coupling system is weak. Therefore,grounded in the research context of "coupling relationship identification-coupling mechanism analysis-coupling process and pattern characterization-coupling management application",we constructed a future research framework on the coupling between the WEF-Nexus and ecosystem services. In addition,it was also proposed that the future research should pay more attention to the exploration of the interaction and coupling mechanism between the WEF-Nexus and ecosystem services,the construction of WEF-Nexus-ecosystem services coupling system and its co-evolution mechanism analysis,and the practical application for territorial space management,so as to meet the national strategic requirements of ecological civilization construction and Beautiful China initiative.
