Evolution characteristics of spatial relationship of land development with economy and society: A case study of Guangdong-Hong Kong-Macao Greater Bay Area
Quantitatively analyzing the spatio-temporal evolution of the relationship of land development with population distribution and economic development has great significance for regional planning and strategy formulation. This paper utilized night light data to fit the population and gross domestic product (GDP) in the Guangdong-Hong Kong-Macao Greater Bay Area. Then the spatial-temporal evolution of the population and GDP was studied with a standard deviation ellipse. Finally, the spatial matching characteristics of land development intensity with the population distribution and economic development were explored by bivariate correlation analysis. The results are as follows. ① There is a significant correlation between night light and population/GDP. ② From 2000 to 2018, the population showed an increasingly concentrated distribution pattern, and the aggregation degree of GDP declined. ③ There is a significant spatial correlation of land development intensity with population distribution and economic development. However, as population and economic development lag land development, there are some low-high clusters on the periphery of high-high clustered areas. The low-high clustered areas will gradually evolve into high-high clustered areas with socio-economic development.
