| description | The scientific prioritization of non-grain cultivated land restoration sequences plays a pivotal role in implementing the occupation and compensation balance, as it simultaneously safeguards national food security and optimizes territorial spatial configurations. Focusing on non–grain cultivated land, this study established a county-level evaluation framework based on Third National Land Survey data. Utilizing an integrated assessment technique, we first quantified the actual restoration potential. Subsequently, a comprehensive time-sequence evaluation system was developed incorporating three key dimensions: restoration potential, urgency and agglomeration. The innovative ‘3D magic cube’ model was then employed to classify restoration priority zones across Shandong's counties, revealing spatial distribution patterns and investment priorities for non-grain cultivated land restoration. Based on these findings, targeted management strategies were formulated. Results demonstrated that the overall cultivated land restoration potential in Shandong Province was relatively high, exhibiting a characteristics ‘central depression with peripheral elevation’ spatial distribution pattern. Furthermore, the restoration urgency was predominantly at medium levels, while displaying significant spatial heterogeneity. The spatial agglomeration degree of cultivated land restoration remained relatively low overall. Additionally, different priority zones formed clustered and continuous spatial distribution. Based on the restoration sequence evaluation, the Shandong Peninsula Urban Agglomeration was classified into three types: priority, general and backup recovery areas, presenting a ''core-periphery'' spatial configuration centered on Jinan and Qingdao metropolitan areas. Western Shandong was identified as the highest-priority restoration zone, with Dezhou, Liaocheng and Heze collectively accounting for 43.33 % of the total priority restoration areas. Consequently, it was essential to clarify the responsibilities of stakeholders in the land use offset mechanism and standardize operational procedures to enhance the effectiveness of non-grain cultivated land rehabilitation. This study established a scientific foundation for selecting cultivated land rehabilitation projects and formulating national-level strategies occupation and compensation balance. |
