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.
Highlights
In the process of urbanization, a variety of problems have emerged, drawing attention to the challenges to rational and sustainable development, such as ecosystem degradation, the spatial mismatch of resources, and inefficient land use
Less attention has been given to production– living–ecological space (PLES) conflicts at the microgrid scale. These factors suggest an urgent need to establish a multiscale integration model to diagnose land use conflicts from the perspective of Against this backdrop, using the example of Yunnan Province, China, this paper aims to contribute to the literature by establishing a systematic multi-objective integration model
We aim to contribute to the literature in three ways: (1) improve multifunctional land use conflict diagnosis, (2) improve the optimization method of land space function zone in typical mountainous areas, and (3) refine the research scale
Summary
In the process of urbanization, a variety of problems have emerged, drawing attention to the challenges to rational and sustainable development, such as ecosystem degradation, the spatial mismatch of resources, and inefficient land use. The need to clarify resource and environmental constraints and to identify risks in regional development remains a core development issue in different parts of the world, e.g., Iran [2], Italy [3], Nepal [4], and recently China [5]. These studies demonstrate the need to coordinate the relationship between resources, environment, and economic development and to more rationally arrange living spaces [6]. The zoning includes agricultural development, urban construction, and ecological protection, and the underlying idea is to draw “three red lines”
