Abstract: In this paper, economic development, ecological environment and social progress were taken as three subsystems and 15 indicators were selected to construct a comprehensive evaluation index system of ecological civilization in Henan Province. The entropy method was used to evaluate and analyze the development of ecological civilization in Henan Province from 2011 to 2020. Finally, the coupling degree and coupling degree of each subsystem of ecological civilization in Henan Province were quantitatively analyzed and classified by constructing coupling coordination degree model. The results showed that the subsystems of ecological civilization in Henan Province were in the basic coupling stage in 2011—2012, and were in the highly coupling stage in other years. On the whole, the coupling coordination degree among all subsystems of ecological civilization in Henan Province showed an increasing trend during 2011—2020, but the overall coupling coordination degree was still low. The research results can provided empirical support and policy advice for the future high-quality development of ecological economy and policy formulation in Henan Province.
