ABSTRACT
Exploring the coupling and coordination relationship and driving factors of the functions of regional production-living-ecological spaces (hereinafter referred to as “Three Spaces”) is of great significance for revealing the interaction mechanism among different spatial types within a region and achieving the efficient and sustainable utilization of territorial space. Taking Guizhou Province, which is typically distributed with karst landforms, as the research area and county-level regions as the analytical units, by using the coupling and coordination level model, spatial autocorrelation model, and geographical detector model and selecting the land use types and statistical data in 2005, 2010, 2015, and 2020, research on the function identification, relationship exploration, and driving factor analysis of the “Three Spaces” in Guizhou Province was carried out. The results are as follows: ① From 2005 to 2020, the functions of the production space and the living space in Guizhou Province generally showed a gradual growth trend, with a spatial pattern characterized by being higher in the central area and lower in the marginal areas. In contrast, the function value of the ecological space was on a downward trend, and its spatial pattern was the opposite. ② The improvement of the functions of the production and living spaces promoted the growth trend of the coupling and coordination degree of the “Three Spaces.” However, the overall coupling and coordination degree was low, and the imbalance in the coordinated development of the “Three Spaces” among various counties was intensifying. ③ The spatial correlation analysis showed that from 2005 to 2020, there was a significant spatial correlation in the coupling and coordination degree of the “Three Spaces” at the county level in Guizhou Province. The spatial agglomeration trend was continuously strengthening, presenting a clustered spatial distribution feature with higher values in the central area and lower values in the marginal areas. ④ The main single factor influencing the coupling and coordination of the functions of the “Three Spaces” in Guizhou Province was population density. Moreover, there were two-factor and non-linear enhancement relationships among various factors. Among them, the interaction between population density and normalized difference vegetation index (NDVI) had the strongest influence on the coupling and coordination degree. The social and economic development based on natural geographical conditions played a driving role in the development of the coupling and coordination relationship of the functions of the “Three Spaces.” Therefore, to achieve the green, low-carbon, and ecologically efficient development of the economy in the karst ecologically fragile areas, it is necessary to rationally optimize the layout of the production-living-ecological spaces and develop the economy based on natural endowments.
