Abstract: The coordinated development of intensive land use and urbanization in urban agglomeration is the core issue of land management. It is of great significance to achieve the high coordination of intensive land use and urbanization, which may promoti the sustainable development of urban agglomeration. Using Generalization Principal Component Analysis, Variation Coefficient Method to improve the accuracy of the index weight, the paper uses coupling degree model and coordination degree model, relative development model to measure, analyze, and compare the coordinated development level of Jingjinji, Yangtze River Delta and Pearl River Delta urban agglomerations. Spatial autocorrelation model is used to explore the characteristics and rules of spatial agglomeration of coordinated development level. The results showed that: The coordinated development level of Jingjinji ranks first, followed by the Pearl River Delta, and Yangtze River Delta. The optimization degree of coordinated development level ranked as follows: Jingjinji, the Pearl River Delta, and the Yangtze River Delta. The spatial correlation of the coordinated development degree ranked as follows: Jingjinji, the Yangtze River Delta, and Pearl River Delta. The coordinated development level in Jingjinji gradually tends to be moderate and high coordination, Yangtze River Delta and Pearl River Delta tend to be moderate and low coordination. The lags of new urbanization development is the main factor to influence the coordinated development level of Jingjinji and Yangtze River Delta in the early study. The new urbanization development of Jingjinji is speedingup and the Yangtze River Delta is in the state of synchronous development in the late of the study. The new urbanization development of Pearl River Delta has achieved great progress, but still lags behind the intensive land use. Key words：intensive land use; new urbanization; the coordinated development degree; Jingjinji, Yangtze River Delta and Pearl River Delta urban agglomerations
