Identification of potential conflicts in the production-living-ecological spaces of the Central Yunnan Urban Agglomeration from a multi-scale perspective

Abstract

The rapid urbanization in China has exacerbated the conflicts among production space, living space, and ecological space (PLES). Balancing economic development with ecological protection on limited land resources presents a pivotal challenge in the urbanization process. Mountainous urban agglomerations, with their complex terrain and limited development space, intensify PLES conflicts. Exploring potential PLES conflicts in these areas is crucial for optimizing spatial layout, coordinating human-land relationships, and promoting high-quality regional development. It is also a significant and challenging area in current research. Using the Central Yunnan Urban Agglomeration (CYUA) as a case study, this study integrated grid and administrative scales, incorporating human-oriented factors. A comprehensive evaluation system for mountain urban agglomerations, including suitability evaluation and spatial carrying capacity assessment, had been established. The conflict recognition matrix was used to identify potential PLES conflicts within the urban agglomeration. The results indicated that the PLES in the CYUA predominantly exhibited moderate levels of suitability. Production space suitability was higher in the southeast and lower in the northwest, living space suitability displayed a distinct strip-like distribution. Ecological space suitability was concentrated in the northeast and northwest, with lower suitability observed in the south. Apart from lake areas, approximately 71.92% of land in the CYUA faced potential conflicts regarding land use, primarily general spatial conflicts accounting for 49.79% of the total area. Intense conflict zones covered the smallest area, representing only 0.04% of the study area. The occurrence of potential spatial conflicts in this region was heavily influenced by both natural environmental factors and human activities. Suitable land areas were notably concentrated in regions with high human activity levels, favorable natural environments, and single land use functions. Conflicts were particularly concentrated in transition zones between human production and living spaces and ecological areas. The findings of this study offer valuable insights for guiding urban planning and management strategies not only for the CYUA but also for other mountainous urban agglomerations facing similar challenges.
