Abstract：In orderto explore the coupling coordination relationship between new urbanization and sustainable land resource utilization in the Yangtze River Delta urban agglomeration from 2O10 to 2O2O and ensure high-quality regional development，this paper took 26 central cities thereas objectsand established an index system.The spatial-temporal parameters and influencing factors of the coupling coordination degree between the two systems are analyzed through the entropy method，coupling coordination degree model，spatial autocorrelationanalysisand geographical detector.The results show that：（1）The level of new urbanization and sustainable land resource utilization in the Yangtze River Delta urban agglomerations showsatrend offluctuating growth;the levelof new urbanization shows a stair-likepatern of higher in the eastand lowerin the west，and the level of sustainable land resource utilization has evolved froma multicore structure to a contiguous expansion.（2） The coupling coordination degree between the two systems is high;the degree increases slowly，from reluctant coordination to primary coordination，presenting a spatial patternof higher in the Southeast，butlower in the Northwest.（3）Spatial agglomeration has a positive effect on the coordination of the two systems.In terms of local spatial autocorrelation，H-H cluster and HL cluster cities increase year by year，while L-L cluster cities decrease year by year;H-H cluster cities are distributed in the southeast and L-Lcluster cities are distributed in the west.（4）The impactof different influencing factors on the coupling coordination degree of two systems exhibits significant temporal heterogeneity，and the per capita disposable income index is the most influential one in 2O1O and 2015;the highest impact indicator in 2O2O is the satisfaction of social needs.Accordingly，the paper puts forward some countermeasures and suggestions to promote the coupling and coordinated development of new urbanization and sustainable utilization of land resources in the Yangtze River Delta city cluster.
