Abstract: The data of Shangluo City from 2009 to 2019 were selected, and the weight index of tourism economy and ecological environment of Shangluo City was determined by entropy method, and then the coupling coordination degree model of tourism economy and ecological environment of Shangluo City was determined, and an effective analysis was made. The results showed that from 2009 to 2019, the comprehensive index of tourism economy in Shangluo City showed a continuously rising trend, and the comprehensive index of ecological environment showed a fluctuating rising state, both of which developed well but still had room for improvement. The coupling degree between tourism economy and ecological environment had maintained a high degree of coupling from 2009 to 2019, and the overall development indicators and coupling coordination degree had shown an upward trend. From 2009 to 2019, the coupling coordination between the tourism economy and ecological environment in Shangluo City shifted from primary coordination to good coordination, and the type of coupling coordination shifted from lagging tourism economy to lagging ecological environment.

Key words: tourism economy, ecological environment, coupling degree measurement model, Shangluo City
