Abstract: Accurately grasp the coupling and coordination relationship between intensive use of cultivated land and ecological efficiency and its temporal and spatial differentiation characteristics, On the one hand, it can better coordinate the relationship between the intensive use of cultivated land and the ecological environment of cultivated land use, and provide a supporting basis for the ecological and green sustainable use of cultivated land within the region; On the other hand, it helps to clarify the evolution law of the coupling and coordination level of the two in the geographical space, and can provide a policy basis for formulating the improvement of the overall coordination of the coordinated area. Based on the analysis of the connotation and coupling mechanism of cultivated land intensive use and ecological efficiency, the level of cultivated land intensive use and the ecological efficiency were estimated by multi-factor comprehensive analysis method and SBM-Undesirable model. The coupling coordination degree model and spatial autocorrelation model were used to explore the coupling coordination level and its Spatio-temporal evolution characteristics. Results show that: (1) From 2007 to 2019, the intensive use of cultivated land in China and the level of eco-efficiency are increasing to varying degrees, and the coupling and coordination of the two are also gradually increasing. On the whole, the coupling coordination degree of cultivated land intensive use and ecological efficiency gradually stepped into the primary coordination stage from the reluctantly coordinated stage in the early stage of the study; (2) There is a spatial positive correlation between the coupling coordination degree of cultivated land intensive use and ecological efficiency in geographical space, but the spatial positive correlation changes from strong correlation to weak correlation over time, the degree of agglomeration is gradually weakened, the discrete characteristics are increasingly prominent, and the spatial differences among provinces are gradually enhanced; Therefore, we should strengthen the intensive utilization of cultivated land is reasonable, enhance the level of cultivated land use of green development, and based on scientific zoning and region-specific policies, actively construct the mechanism of synergy between neighboring provincial to promote cultivated land-intensive utilization and ecological efficiency between the coupling coordination level.
