Abstract: Ecosystem services are irreplaceable for human well-being. Based on the method of literature review, the research progress and trend of ecosystem services were summarized. Firstly, the concept and connotation of ecosystem services were expounded. Secondly, the research progress of ecosystem services were combed in terms of the monetary value evaluation of ecosystem services, the supply-demand balance and transfer of ecosystem services, and the trade-offs and synergies of ecosystem services in China and abroad. Thirdly, it was proposed that the internal relationship of ecosystem pattern-process-function-services would be the focus of ecosystem services research, the supply-demand and spatial transfer of ecosystem services would become an important research direction, the trade-offs and synergies of ecosystem services would be an important part of ecosystem management research, and the feedback mechanism of ecosystem services and human well-being would be further studied. The research would help to scientifically understand the supporting role of ecosystem services for the sustainable development of human society, and to promote the application of ecosystem services research results to practice.
