The progression traits of spatial conflicts within the production–living–ecological space among varying geomorphological types of mountain–basin areas in karst regions, China
Abstract
Owing to the fragile ecological environment and the prominent human–land conflict relationship, the competition between land multifunctionality in the karst region has increased. In this context, the coordination and stability of production–living–ecological space (PLES) have been severely affected, and the scientific diagnosis of PLES conflict characteristics can provide an important basis for optimizing national land allocation. Using land use data, this study used a spatial conflict measurement model to examine the spatial and temporal variations of PLES conflicts across mountain–basin areas of various geomorphological in karst types. Meanwhile, the factors influencing their evolution were also investigated. The study results showed that the ecological space (ES) area was the largest in the study area and had an increasing trend from 2010 to 2020. PLES conflicts were dominated by stable and controllable, and light conflicts, and the overall conflict level had increased. Influenced by the natural environment, socioeconomics, and policies, there were significant differences in the development of PLES conflicts in the mountain–basin areas. The conflict level in the basin area was higher than in the mountain area. The intensity of PLES conflicts in the mountain–basin areas in the karst valleys geomorphic types and in the mountain areas in the karst fault basin showed a decreasing trend. The level of conflicts in the mountain–basin areas in the karst plateau, karst peak–cluster depression, karst trough valley geomorphic and in the basin area of the karst fault basin geomorphic type showed an increasing trend. There were also common evolutionary characteristics for PLES conflicts in mountain–basin areas. The findings have provided a reference to support differentiated land management and decision-making in karst areas, which can contribute to the strategic sustainable development at the regional level.
