Abstract:
Spatial zoning of cultivated land is fundamental to achieving differentiated management and sustainable development. This study integrates Resilience Theory and Morphological Spatial Pattern Analysis (MSPA) to optimize cultivated land structure-function synergy, proposing pathways to enhance disturbance resistance and sustainability. Taking the Chengdu-Chongqing Region (CCR) as the study area, a three-dimensional Cultivated Land Resilience (CLR) evaluation framework was constructed based on "Morphological Stability-Productive Vitality-Adaptive Resilience", innovatively incorporating spatial indicators (e.g., connectivity, fragmentation). The AHP-CRITIC weighting and K-Means clustering were employed for resilience assessment and zoning. Key findings reveal: (1) A dual-core driving mechanism where topographic fragmentation (peripheral mountains) and urban encroachment (suburban belts) jointly degrade spatial connectivity; (2) Spatial heterogeneity characterized by gradient attenuation from core plains to marginal mountains, with specific quantification showing high-resilience plains (e.g., Zone 6) achieving 1.66 times higher grain yield per unit area (0.0430) and nearly 6-fold greater morphological connectivity (0.0315) compared to degraded slopes (e.g., Zone 9 with 0.0259 yield and 0.0055 connectivity); (3) Nine resilience-based zoning types forming a governance spectrum: Conflict Zones (development-protection balance), Potential Zones (industrial chain optimization), Degradation Zones (ecological restoration). This framework enables a shift from homogeneous control to spatially precise governance, providing a scientific basis for sustainable cultivated land management in rapidly urbanizing regions.
