Ecosystem services bridge the natural environment and human well-being, and are the key content of coupled human-environment system research. This article puts forward a framework of research on ecosystem services for coupled human-environment systems, and systematically reviews the research hotspots of ecosystem services evaluation, ecosystem services trade- offs, ecosystem services driving factors, ecosystem supply- flowdemand, and identifies the key areas for future ecosystem services research. This article argues that: (1) international research on ecosystem services models have experienced a rapid development, and SAORES model is the outstanding representative of ecosystem service evaluation model in China; (2) ecosystem service trade-off analyses are relatively complex, and its mechanism depends on distinguish the relationships among ecosystem structure- process- function- service at multiple spatial and temporal scales; (3) natural factors are the basis of ecosystem services distribution, land use change can modify ecosystem structure, function, and services, and social and economic factors can lead to differences in ecosystem services trade-off and demand; (4) in order to clarify the coupling relationship between ecosystem service supply and demand, it is urgently needed to further identify the pathes of ecosystem service flowes; (5) future research of ecosystem services should include strengthening the analyses on the response of ecosystem services to global change, ecosystem services supply and demand flow focusing on the sustainable development aspect, integration and optimization of the dynamic evaluation of ecosystem services, the coupling of ecosystem services and human-environment systems, and the integration of ecosystem services and big data.
