A framework for identifying the distribution of revitalization potential of idle rural residential land under rural revitalization

Idle rural residential land (IRRL) serves as a crucial resource for rural land utilization. Evaluating its potential for revitalization forms the foundational research in rural land consolidation. In the context of rural revitalization, quantitatively determining the potential to revitalize IRRL is a fundamental scientific investigation, requiring focus within the field of rural land sustainability research. In our study, we have developed a framework for identifying IRRL revitalization potential under rural revitalization, combining with the village development environment and self-characteristics of IRRL, and have proposed a classification method of IRRL revitalization types. Our results found a spatial mismatch between the IRRL revitalization potential and the external conditions of consolidation potential release. Compared with the IRRL consolidation potential based on spatial characteristics, the vitality of rural revitalization in Pinggu is small, which is manifested as low vitality of rural revitalization and surplus revitalization potential. Under rural revitalization, the IRRL revitalization potential in Pinggu is low. In the central agricultural and eastern semi-mountainous regions, IRRL plays a pivotal role in land reutilization within the context of rural revitalization. Moderate revitalization is the dominant revitalization type. The revitalization of IRRL in the central agricultural and eastern semi-mountainous regions plays a pivotal role in the reuse of residential land within rural revitalization. The prominent revitalization type is characterized as moderate revitalization. Considering the diversity of rural revitalization in Pinggu, the revitalization of IRRL should prioritize meeting a range of land usage needs within the rural revitalization context. Furthermore, it should capitalize on surplus potential through strategies like spatial transfer or retaining idle IRRL. Our research aims to foster a fresh perspective on the potential for revitalizing IRRL within the rural revitalization framework, emphasizing rural regional systems. This, in turn, can facilitate the harmonization of IRRL utilization with rural development, offering theoretical underpinning for human-land coordination and sustainable rural development in developing nations.
