Research on land use pattern change and its influencing factors based on the coupling model: evidence from Zhongshan, China

The change in the land spatial structure affects regional development and stability. In the context of the construction of the Guangdong-Hong Kong-Macao Greater Bay Area, studying the spatial structure changes in its important cities will contribute to the coordinated development of the region. This study uses spatial analysis and coupling models to explore the basic characteristics and evolutionary trends of the land spatial structure in Zhongshan city in 2000, 2011, 2022, and 2035. Through research, it is found that (1) in general, the urban space is divided into different geometric forms by the water network system. The spatial structure of living land is 'fragmentation-aggregation-aggregation and fragmentation'. (2) Ecological land is concentrated in the southeast and remained relatively stable. Productive land accounts for the largest proportion in Northeast China, becoming the main area of agricultural development. (3) From 2022 to 2035, the area of productive land will increase in different ranges under four scenarios, and the area of productive land will increase the fastest under the urbanization development scenario (UDS). (4) The ecological land area increases only in the ecological protection scenario (EPS), and the area decreases in the other three scenarios. An increase in construction land area occurs in the urbanization development scenario (UDS) and nature development scenario (NDS). (5) The habitat quality of Zhongshan city showed a significant decline from 2000 to 2022. In 2035, the habitat quality will significantly improve in the ecological protection scenario (EPS) and sustainable development scenario (SDS) scenarios, and the ecological regions in Southeast China will be significantly clustered and expanded.

Automated summary

The change in land spatial structure has a significant impact on regional development and stability. Studying the spatial structure changes in important cities, such as Zhongshan city, contributes to the coordinated development of the region. The research finds that the urban space in Zhongshan city shows a pattern of fragmentation, aggregation, and fragmentation in terms of the spatial structure of living land. Productive land is concentrated in the northeast and ecological land is concentrated in the southeast. From 2022 to 2035, productive land will increase in different scenarios, with the fastest increase in the urbanization development scenario. The habitat quality of Zhongshan city has declined from 2000 to 2022 but is expected to improve in the ecological protection and sustainable development scenarios by 2035.
