To explore the spatial-temporal coupling coordination relationship between land intensive use and regional high-quality development in Yijingjing metropolitan area, AHP(analytic hierarchy process) and entropy method were used to evaluate and measure the land intensive use and regional high-quality development from 2010 to 2022, and then the coupling coordination between the two was analyzed based on the coupling coordination degree model and the improved Tapio coupling index. The results show that the comprehensive index of land intensive use and regional high-quality development maintained positive growth, and the development trend of the latter was more stable and rapid than that of the former, showing a distribution pattern of “high in the central and eastern regions and low in the western regions”. The comprehensive index of land intensive use and regional high-quality development shows the status quo of coordination and discoordination, and the coordination degree is more and more dominant, especially in Jingzhou City, which has mainly shown the land-leading coupling and growth coupling since the “14th Five-Year Plan”. With the promotion of policies and the implementation of measures, the land economic system of Yijingjing metropolitan area is increasingly coordinated and reasonable, and the intensive use of land still needs to be promoted efficiently.
