Abstract:: [Objective] Understanding the coupling coordination relationship and spatial differences between population urbanization and land urbanization in the urban agglomerations is not only the key to expedite the rational allocation of human and land resources in urbanization process, but also of great significance to China's new urbanization initiative, which promotes healthy, scientific and sustainable urban transition. [Methods] The Beibu Gulf Urban Agglomeration(BGUA)was taken as a case. Based on the interaction between population urbanization and land urbanization, population urbanization and land urbanization quality evaluation index system was constructed, and the population-land urbanization quality and spatiotemporal characteristics from 2005 to 2019 were measured. Meantime, the coordination relationship between population urbanization and land urbanization was quantitatively analyzed and discussed by using the elastic coefficient, coupling coordination degree model and kernel density estimation method. [Results](1)Although the overall urbanization level of BGUA was relatively low and the quality of urbanization varied significantly among cities, the qualities of population urbanization and land urbanization in the BGUA both showed an increasing trend.(2)Contrast type of population urbanization and land urbanization always appeared to land lag, these cities accounted for 60%. About 26.67% of cities were that population urbanization lagged behind that of land urbanization, while 13.33% of cities were population-land urbanization synchronous type.(3)The overall coupling coordinated degree of population-land urbanization in the BGUA showed a general upward trend, and its spatial differences tended to narrow. In space, the coupling coordination degree of Haikou City was the highest(0.915)and belonged to high-quality coordination type, followed by Nanning and Beihai City with the coupling coordination degrees of 0.796 and 0.744, respectively. The coupling coordination degrees of the other cities were relatively low and experienced a change from mild non coordinated type to slight and medium coordination type. [Conclusion] From 2005 to 2019, the spatial differences in the coupling and coordination relationship between population urbanization and land urbanization in the BGUA showed a clear trend of improvement. From the perspective of promoting the benign and coordinated development of urbanization in various cities, the BGUA was divided into five types based on different levels of urban development and coupling coordination degrees, and the innovatively differentiated population land urbanization development strategies and countermeasures were proposed according to local conditions.
