- Abstract:
- [Objective] The aims of this study are to explore the coupling and coordination relationship and influencing factors of regional production-living-ecological spaces(PLES)function, and to guide the optimization of regional land spatial pattern and realize high-quality sustainable development. [Methods] Kunming was taken as an example. Based on the construction of the evaluation index system of the spatial function of PLE, Entropy weight method, linear weighting method, ternary diagram and coupling coordination degree model were integrated to quantitatively measure the spatial and temporal characteristics of the coupling and coordination of the spatial function of PLE in Kunming from 2000 to 2020, and geographical detectors were used to explore the dominant factors affecting the development of the spatial function of PLE in Kunming. [Results](1)From 2000 to 2020, the PL space function of Kunming City showed an overall upward trend, and the ecological space function showed a downward trend. Driven by policy measures and project construction site selection, the urban function positioning changed. The PLES function mainly experienced the EL and PLE advantage equilibrium area, and it was found that 2010 was an important turning point for entering the balanced development of PLE.(2)In the past 20 years, the overall fluctuation of the functional coupling coordination degree of PLE in Kunming City had been small, and it had experienced the basic coordination and moderate coordination stages, showing a pattern of high level around and low level in the middle in space.(3)The main factors affecting the coupling and coordination of PLES functions in Kunming were the per capita sown area and forestland area, and the interaction of factors increased the explanatory power of the development of PLES functions. [Conclusion] Among them, the habitat quality is less stable and volatile in the development of PLES functions.
