Analysis of the Spatial-temporal Evolution of Land Use and Driving Force based on the Production-Living-Ecological Space: A Case Study of Shenzhen

Exploring the evolution of land use and its driving force in Shenzhen's Production-Living-Ecological Space (PLES) may serve as a reference for optimizing regional land spatial patterns and urban spatial structures, as well as providing a scientific foundation for supporting regional sustainable development. The research period was 2010 to 2020, and the spatial-temporal evolution was analyzed using GIS and a land use transfer matrix, followed by an examination of the driving factors of its change using geographic detectors. The results indicate that: (1) Shenzhen's production space increases initially before decreasing, while the living space increases little and then grows significantly, while the ecological space continues to shrink significantly. (2) From 2010 to 2015, the degree of conversion was quite low, but from 2015 to 2020, it climbed dramatically. (3) The majority of the factors have strong explanatory power for the land use intensity of PLES but the annual average temperature, NDVI, and the added value of tertiary industry are always important driving factors influencing the land use intensity (4) In the interactive detection, the average annual temperature, NDVI, PM2.5, population density, and the added value of tertiary industry were interacted with other factors, and the results significantly increased the explanatory power of the land use intensity of PLES.
