Abstract: The Yangtze River Economic Belt is one of the areas with the sharpest human-land conflict in China. In recent years, the rapid development of the Yangtze River Economic Belt has caused a great negative impact on regional ecosystem services. It is of great significance to realize the sustainable development of the region to deeply understand the spatio-temporal evolution process and coupling coordination between ecosystem services and economic-social development. Based on the analysis of the spatio-temporal pattern of economic-social development and ecosystem service value in the Yangtze River Economic Belt, the study analyzed the spatio-temporal evolution characteristics of the coupling coordination between them. The results show that: (1) From 1995 to 2015, the level of economic-social development in the Yangtze River Economic Belt showed a significant upward trend, and the ecosystem service value declined significantly after 2005, which was consistent with the acceleration period of economic-social development. At the same time, the coupling coordination degree between economic-social development and ecosystem service value in the Yangtze River Economic Belt shows an overall upward trend, and there are significant spatial differences in the coupling coordination degree among provinces. (2) Chongqing, Jiangsu, Anhui and Sichuan experienced rapid economic-social development during the study period, but ecosystem protection lagged behind the economic-social development, which made them from the backward areas of economic-social development to the backward areas of ecosystem services at the end of the study. It shows that these provinces have damaged the capacity of natural ecosystem to some extent with the rapid economic-social development. The economically developed provinces in the middle and downstream of the Yangtze River Economic Belt are faced with the problem of how to coordinate the relationship between social development and ecological protection, while the economically less developed provinces in the upstream of the Yangtze River Economic Belt are faced with the dual pressure of improving the level of economic-social development and ecological protection.
