Abstract: It is very important to explore the coordinated development between industrial ecologicalization and ecological industrialization for promoting the high-quality development of the Hanjiang River Ecological Economy Belt, at the background of improving the level of ecological environment governance across the whole country. This paper takes nine cities of Hanjiang River Ecological Economy Belt as the research object， and adopts entropy method and coupling coordination model to measure the level of industrial ecologicalization and ecological industrialization, according to the data from 2011 to 2019. The evolutional features of coupling and coupling coordination degree of industrial ecologicalization and ecological industrialization are analyzed by using the method of GIS. The study shows that: firstly, the overall level of industrial ecologicalization is on the rise, the pattern of gradient distribution gradually indicates ongoing increase in upper, middle and lower reaches of Hanjiang River Ecological Economy Belt. Secondly, the level of ecological industrialization shows a steady growth, the pattern of gradient distribution presents gradually diminishing in upper, middle and lower reaches of Hanjiang River Ecological Economy Belt. Thirdly, the coupling degrees of industrial ecologicalization and ecological industrialization are on the rise，the coupling type is in the transition from runin stage to highlevel stage. Fourthly, the couplingcoordination degrees of industrial ecologicalization and ecological industrialization are showing a rapid growth, the coordination type has been developed from reluctantly couplingcoordination to good couplingcoordination. Suggestions are put forward including boosting the green development of agriculture and industry, constructing a multiplelevel system of resource saving and reusing, and elevating the coordinated development between industrial ecologicalization and ecological industrialization in Hanjiang River Ecological Economy Belt synergistically.
