Abstract: Exploring the coordinated development of the tourism industry and the eco-environment is very crucial to break the bottleneck of the transformation and upgrading of the tourism industry and initiate the new situation of ecological civilization construction in the Yangtze River Economic Belt. Based on the construction of the evaluation index system of development status, this paper validates the interactive coercive relationship between tourism industry and ecological environment system based on the interactive coercion model, and then using the coupling coordination model, spatial gravity model and other methods, the dynamic evolution characteristics and spatial connection structure of the two systems in the Yangtze River Economic Zone since 1998 are analyzed empirically. The results show that: (1) The evaluation values of the two major systems of the tourism industry and the ecological environment in the Yangtze River Economic Belt both show an increasing trend, and the disequilibrium between regions gradually weakens; (2) There is an interactive stress relationship between the tourism industry and eco-environment in the Yangtze River Economic Belt, and the evolution trajectory conforms to the rhythmic development characteristics of a combination of multiple S-shaped curves; (3) The coordinated development stage of the complex system of the Yangtze River Economic Belt roughly experienced the following evolution process: mild imbalance (1998-2006)-endangered imbalance (2007-2015)-rough coordination (2016-2017); (4) The spatial connection pattern of the regional coupling coordination degree of various provinces and regions is getting closer and closer, and the connection potential energy is steadily increasing. The overall pattern presents a step-type decreasing pattern of “extrude in east-uplift in central-collapse in west”, and the interior of the three major regions also shows significant non-equilibrium characteristics.
