Multi-Objective Spatial Suitability Evaluation and Conflict Optimization Considering Productivity, Sustainability, and Livability in Southwestern Mountainous Areas of China

Abstract

Space is the fundamental carrier for production, living, and ecological activities, and optimizing the spatial pattern is of vital importance to promote regional sustainable development. To achieve this goal, the core issues are to identify the risks of resource and environmental constraints of development and to realize the rational distribution of human living space. Based on the integration of multisource heterogeneous data, taking Yunnan Province, a typical mountainous area in China, as an example, this research proposes a multi-object suitability evaluation method based on 50 × 50 m grid data at the provincial scale. We build a spatial conflict analysis model to identify production–living–ecological space (PLES) and propose governance suggestions for different functional areas. The results show that (1) areas suitable for ecology make up the greatest proportion of Yunnan Province, but areas with living and ecological functions show obvious spatial complementarity; (2) areas suitable for production are restricted by steep slope, geological hazards and fragmented pattern; (3) areas suitable for living is rare, and they are mainly concentrated in the plains of central Yunnan; and (4) twenty-seven percent of area has potential spatial conflicts, among which 4.38% of the area is all suitable for production–living–ecological. The production–living advantage areas are concentrated in the central Yunnan UA (Urban agglomeration), which has a high spatial overlap. These results are expected to provide valuable insights to support comprehensive multifunctional spatial utilization and sustainable development in mountainous areas.

Eco-environmental effect and driving factors of changing “production-living-ecological space” in northern Xinjiang, China

“…According to the functional attributes of land, China's land is divided into production space, living space and ecological space, which can more intuitively observe the evolution of land use kinetic energy. At present, the relevant research on "productionliving-ecological space" (PLES) mainly focuses on the connotation framework (Lin et al, 2022), classification system (Fu et al, 2022), function recognition (Tao and Wang, 2021), structure evolution (Gao et al, 2022), driving mechanism (Wang et al, 2022), coupling coordination (Cui et al, 2022), function conflict (Fang et al, 2022), scenario simulation (Jiang et al, 2022), and spatial optimization . Few studies have linked the evolution of PLES with the eco-environmental quality of grid cells or discussed the evolution characteristics and spatial differentiation mechanism of eco-environmental effects of land-use transition (Dong J. H. et al, 2022;Li and Wu, 2022;.…”

Response Characteristics of Soil Erosion to Spatial Conflict in the Production-Living-Ecological Space and Their DrivingMechanism: A Case Study of Dongting Lake Basin in China

“…Jing et al [26] identified potential land use conflicts by constructing a multi-objective suitability evaluation index system for production, living, and ecological land uses. Fang et al [27] discerned spatial conflicts in the PLES of southwestern China's mountainous areas by constructing a multi-objective suitability evaluation model considering productivity, sustainability, and liability, and proposed governance recommendations for different functional units. Multiple suitability requirements of land use, scarcity of land resources, and diversity of human needs are fundamental causes of land use conflicts [28].…”
