| 中文摘要: |
| 耕地“占补平衡”与“进出平衡”是架构我国耕地保护政策体系的制度核心，可补充类耕地资源整治是落实耕地保护“双平衡”政策的重要途径。本研究基于耕地保护“双平衡”政策视角，探索性地提出了可补充类耕地资源的概念内涵及其适宜性评价指标体系，并采用多因素综合评价、SOFM等方法对广东省县域单元可补充类耕地资源适宜状况进行评价、分级与整治分区。结果表明：广东省可补充类耕地资源较为丰富，其中后备补充类、即可补充类与工程补充类的面积占比分别为19.69%、35.72%、44.59%，大量可补充类耕地资源当前为林果产品和水产品生产用地。广东省可补充类耕地资源整治适宜性从高到低分为高度适宜、较高适宜、中度适宜、较低适宜、低度适宜5个等级，其面积占比分别为14.20%、33.69%、22.42%、17.74%和11.95%，适宜程度较高地区主要分布在西翼、东翼与肇庆市。广东省可补充类耕地资源优先整治区、重点整治区、选择整治区与后备整治区的农业生产环境差异较大，为此需要差异化地采取行政干预、工程提质、组织引导、激励奖补等措施。本研究可为指导广东省耕地保护“双平衡”政策的调整、制定与落实提供参考，并对保障区域粮食安全与促进农业可持续发展具有重要的理论与现实指导意义。 |

| The policies of requisition-compensation balance and transfer in/out balance for cultivated land are institutional innovations that facilitate cultivated land protection, and supplementary cultivated land consolidation is an important way to implement the“dual balance” policy of cultivated land protection. In this paper, from the perspective of the“dual balance”policy of cultivated land protection, the concept and suitability evaluation index system for supplementary cultivated land resources have been proposed. Moreover, using multifactor comprehensive evaluation and SOFM methods, the suitability of supplementary cultivated land consolidation in county units in Guangdong Province was evaluated, graded, and zoned. The results showed that the area percentages of reserve supplementary cultivated land, immediately supplementary cultivated land, and engineeringly supplementary cultivated land were 19.69%, 35.72%, and 44.59%, respectively, and many supplementary cultivated lands were currently used to produce fruit, timber, and aquatic products. The area of supplementary cultivated land resources in Guangdong Province accounted for 14.20%, 33.69%, 22.42%, 17.74%, and 11.95% from high suitability grade to low suitability grade, and the areas with higher suitability were mainly distributed in the west, east, and Zhaoqing City. The agricultural production environments of Guangdong Province's supplementary cultivated land resources in the priority consolidation zone, key consolidation zone, selected consolidation zone, and reserve consolidation zone are quite different, so it is necessary to adopt different measures such as administrative intervention, project quality improvement, organizational guidance, incentive, and compensation. This study can provide scientific reference for guiding the adjustment, formulation, and implementation of the“dual balance”policy of cultivated land protection in Guangdong Province, and it has important theoretical and practical significance for ensuring regional food security and promoting sustainable agricultural development. |
