Abstract:

In order to address issues in cultivated land management such as difficulties in cross-department and cross-level collaboration, incomplete resource allocation, weak life-cycle information linkage and insufficient intelligent decision-making support, this study aims to explore a feasible path for the full lifecycle management of cultivated land under the "Two Unifications" framework for natural resource management. Adhering to the concept of trinity protection of "quantity-quality-ecology" of cultivated land, a three-phase development approach involving intelligent data governance, the construction of a cultivated land protection resource database, and the development of a business support platform was proposed. Utilizing integrated sky-air-ground monitoring technology, a full-cycle management framework was established to connect the seven key stages of cultivated land: designation, occupation, replenishment, protection, reservation, remediation, and restoration. Practical scenario implementation was carried out in Mianning County, Sichuan Province. The results demonstrated that the implementation of the ‘Farmland Steward’ full lifecycle supervision process successfully ensured the authenticity, accuracy, comprehensiveness and dynamic updating of cultivated land information. This approach significantly enhanced the refinement of cultivated land protection, improved government decision-making efficiency and ultimately achieved the management objectives of "stabilizing the base area, balancing the quantity, improving the quality, and strengthening the ecology". The study offers practical and replicable experience for cultivated land management across various regions in Sichuan Province.
