Abstract:: In order to explore the coordinated development level of regional urbanisation and ecological environment, taking the Yangtze River Economic Belt as an example, constructing a related theoretical framework based on the perspective of urban land use efficiency and ecosystem health, and comprehensively using the SBM-Undesirable model, the VOR model and the coupling coordination degree model to calculate urban land use efficiency and ecosystem health in the Yangtze River Economic Belt, the coupling and coordination characteristics of the two was analysed, and problem areas of coordinated development were identified. The results show that:(1)The annual average value of urban land use efficiency in the Yangtze River Economic Zone is 0.746 from 2005 to 2018, and the overall trend is slow and fluctuating, with significant spatial agglomeration characteristics. The average value of ecosystem health score is 0.473, showing a slight fluctuation trend as a whole, and showing significant north-south differentiation in geographical space;(2)The mean value of urban land use efficiency and ecosystem health coupling coordination degree increased slightly in the interval of 0.611 to 0.624. As of 2018, 92.62% of the cities in the region have achieved coordinated development, and the results of the coupling are spatially transformed from ‘relatively random' to ‘high in the south and low in the north';(3)Urban land use efficiency and ecosystem health coupling coordination problem areas mainly exist in some cities in the central and lower reaches of the Yangtze River Economic Belt. The main reason is that urban land use efficiency or ecological system health is unilaterally lagging, which inhibits the improvement of the level of urban coordinated development. In general, the degree of mutual influence and promotion between urban land use and ecosystems in the Yangtze River Economic Belt is gradually deepening, and the coupling system formed in the interaction process has basically achieved stable development.
