基于“三调”数据的济南市永久基本农田划定和耕地保护研究

探索永久基本农田划定的有效路径,划定质优、集聚耕地为永久基本农田,有效配置耕地资源,对耕地保护和保障粮食安全具有重要意义。本文基于济南市“三调”成果,从多维度构建耕地综合质量和“可恢复”耕地潜力评价指标体系,根据评价结果将济南市耕地划分为优质、较优质、良好、一般、较差、不稳定与生态保护6种类型,将济南市“可恢复”耕地潜力划分为优先恢复区、适宜恢复区、不宜恢复区。客观反映了耕地综合质量和“可恢复”耕地潜力状况,得到济南市耕地和“可恢复”耕地的资源时空配置,为济南市及其他市县永久基本农田划定提供借鉴,为耕地资源差别化管控和耕地“进出平衡”方案编制实施提供参考。

Study On Permanent Basic Farmland Delineation and Cultivated Land Protection In Ji'nan City Based on the Data of the "Third National Land Survey"

It is of great significance for the protection of arable land and the guarantee of food security to explore an effective way for the demarcation of permanent basic farmland, designate highquality and concentrated arable land as permanent basic farmland, and effectively allocate arable land resources. Based on the results of the "Third National Land Survey" in Ji''nan city, an evaluation index system of comprehensive quality of arable land and the potential of "recoverable" arable land from multiple dimensions have been built. According to the evaluation results, the cultivated land in Ji''nan city has been divided into six types, they are highquality, relatively highquality, good, general, poor, unstable and ecological protection. The potential of "recoverable" arable land in J''inan city has been divided into priority restoration areas, suitable restoration areas and unfavorable restoration areas. It objectively reflects comprehensive quality of arable land and the potential status of "recoverable" arable land, obtains the spacetime allocation of arable land and "recoverable" arable land resources, provides references for the delineation of permanent basic farmland in Ji''nan city and other cities and counties, and provides references for the preparation and implementation of the differential management and control of arable land resources and the "in and out balance" of arable land.
