Cultivated land plays a pivotal role in ensuring national food security,particularly in populous nations like China,where substantial investments are made to develop cultivated land as a counterbalance to construction-occupied areas.Consequently,long-term,effective monitoring of the utilization of newly cultivated land becomes imperative.This study intro-duces a comprehensive monitoring framework,designed for refined scales,that leverages remote sensing data.The framework focuses on the sustainable utilization of newly cultivated land,emphasizing utilization sustainability,productivity stability,and landscape integration.Its effectiveness was validated through a case study in Guangdong province,China.The results revealed satisfactory utilization sustainability and improved productivity stability of newly cul-tivated land in Guangdong,though landscape integration showed sub-optimal results.Fur-thermore,the comprehensive evaluation categorized the newly cultivated land into three lev-els and eight types.The study recommends enhancing the site selection process for newly cultivated land and improving the long-term monitoring,as well as incentive and constraint mechanisms,for their utilization.This study can provide a scientific reference to bolster the implementation of cultivated land protection policies,thereby contributing significantly to high-quality economic and social development.
