The Spatiotemporal Coupling Coordination Model Between Socioeconomic Activity and Eco-environment and Climate Factors: Case Study of Guangdong-Hong Kong-Macao Greater Bay Area, China

Urbanization demands high-quality coordinated development of human-earth relationship. Although a large number of studies have explored the long-term and large-scale coupling effects of urbanization and eco-environment, there is a lack of fine-scale research. Therefore, this paper constructs a coupling coordination model in urban agglomeration based on multi-source remote sensing images, aiming to explore the relationship between climate factors, human activity and vegetation changes of Guangdong-Hong Kong-Macao Greater Bay Area during the period of 2001 to 2018. The results show that the coupling coordination degree in the urban core area showed a slight downward trend, while the high-intensity human activity areas around the urban core area showed an upward trend. The climate factors, human activity and vegetation changes of the urban agglomerations have not reached a highly coordinated coupling stage and high quality coordination. The annual analysis and assessment realize monitoring and comparative analysis of the coordinated development degree of human-earth relationship in urban agglomerations, and provide theoretical support for urban agglomeration development planning.
