Abstract:

Suitability analysis is conducive to the reasonable layout of rural production, living, and ecological space, and is of great significance for coordinating rural land planning in the implementation of rural revitalization strategy in China. On this basis, landscape ecological risk assessment further supports the sustainable and high-quality development of rural areas. From the perspective of production-living-ecology spatial framework, this study establishes a hierarchical evaluation index system for spatial suitability and constructs a landscape ecological risk assessment model at the village scale. The results of the case study in Zhaojiayu Village, Jizhou District, Tianjin, indicate that the most suitable highly suitable areas for ecological space are mainly concentrated in the eastern and southeastern parts of the village. For production space, the most and highly suitable areas are predominantly located in the northern part of the village, while low-suitability and unsuitable areas are mainly found in the south. Living space is primarily composed of most, high, and moderately suitable areas, distributed in the northern region. The landscape ecological risk, ecological space exhibits low risk, with woodland and shrub areas showing the lowest levels. Living space presents a moderate level of risk, while production space demonstrates high risk—particularly in areas designated for tourism production, where the risk is highest. Based on these findings, targeted spatial adjustments and improvements are proposed to support the development of ecological civilization in the village.
