Optimizing the spatial pattern of rural stock construction land is crucial for resolving the imbalance in urban-rural land resource allocation and advancing rural revitalization. While existing studies predominantly focus on urban construction land, this research addresses the insufficient attention to rural stock land. By revealing spatial agglomeration and fragmentation characteristics, it provides insights for formulating differentiated land consolidation policies and promoting integrated urban-rural development. This study holds significance for optimizing rural “production-living-ecological spaces” and fostering rural revitalization. Utilizing survey data from Ningbo City, we constructed a multidimensional evaluation model integrating kernel density analysis, geographic concentration index, and fragmentation index to investigate rural stock construction land at municipal and county scales. Key findings include: ① Rural stock land in Ningbo exhibits a “globally scattered, locally clustered” distribution pattern. ② All four land-use types demonstrate significant spatial agglomeration. ③ Cixi, Zhenhai, and Beilun are identified as Grade-Ⅰ fragmentation zones with high intensive-use potential. The study validates the applicability of the multidimensional model in rural land spatial analysis and proposes a differentiated zoning governance strategy. These results offer theoretical references for county-scale territorial spatial planning in similar regions, advocating “categorized guidance and zoned implementation” to enhance rural land consolidation and revitalization.
