Abstract: To promote the coordinated development of the Changjiang River Economic Belt, improve water resource efficient utilization and ensure shipping development, we construct an indicator system for the water resource utilization and shipping development of the entire Changjiang River Basin and establish a coupling coordination model to analyze the coordination of water resource utilization and shipping development from 2010～2020 in the Changjaing River Basin.And we analyze the relationship between water resource utilization and shipping development in dry years(2011,2017) and extreme conditions(2022).The results show that the coupling coordination degree of shipping and water resource utilization in the Changjiang River Basin has been generally between 0.6 and 0.7 under conventional conditions.In terms of time, the current water resources have not constrained the shipping development of the Changjiang River, and the relationship between the two is generally stable at the primary coordination level, showing a trend of oscillating and rising.In terms of space, there are differences in the coordination level of shipping development and water resource utilization in different sections of the Changjiang River.The coupling coordination degree is higher and more stable in the middle and lower reaches, and lower but steadily increasing in the upper reaches.In unconventional situations(dry years and extreme conditions),the utilization of water resources during drought years may have a certain adverse effect on some sections of shipping, and extreme conditions like “anti-drought during the flood season” in 2022 may also affect shipping safety and efficiency.However, through the optimization of water resource allocation, the water resource level can meet the navigation conditions and guarantee the shipping development.
