| 永久基本农田布局优化的研究对保护耕地和保障粮食安全都具有重要的意义。为了实现立足于耕地数量、质量、生态三位一体理念的永久基本农田空间布局快速优化，本研究选取广东省罗定市作为研究区，从耕地数量、耕地质量、空间形态、空间规划和生态环境等5个层面构建永久基本农田布局优化指标体系。同时，以GIS技术作为分析工具，采用综合指标评价法对罗定市的永久基本农田空间布局进行现状分析及布局优化研究。结果表明，从空间分布来看，调整前后的永久基本农田分布格局基本一致，主要呈中间密四周疏、东西密南北疏的布局特征。布局优化后罗定市的永久基本农田总面积增加了5.2 hm2，相较于调整前的永久基本农田空间布局合理性也有了大幅提高。总体而言，优化调整后的罗定市永久基本农田不仅确保了耕地数量，提升了耕地质量，优化了空间形态，而且改善了罗定市的生态环境，其空间规划也得到了一定程度的优化提升。研究表明：耕地地块布局合理性的评判对永久基本农田划定工作具有重要作用，未来可根据现状耕地和永久基本农田的布局合理性进行永久基本农田的调入、调出，有效推进罗定市永久基本农田划定工作进程；而立足于耕地数量、质量、生态三位一体理念的罗定市永久基本农田布局快速优化方法，也为全国其他粮食主产区的永久基本农田划定工作提供了借鉴及参考。 |

| Research on the layout optimization of permanent basic farmland is essential for protecting arable land and ensuring food security. To achieve rapid spatial layout optimization of permanent basic farmland based on cultivated land quantity, quality, and ecology, this study selected Luoding City Guangdong Province as the research area, constructing an optimization index system for a permanent basic farmland layout from five levels:cultivated land quantity, cultivated land quality, spatial form, spatial planning, and ecological environment. At the same time, this study used geographic information system technology as an analysis tool and a comprehensive index evaluation method to analyze the current situation and optimize the permanent basic farmland spatial layout in Luoding City. Results show that from the perspective of spatial distribution, the distribution pattern of permanent basic farmland in Luoding City before and after the adjustment is essentially the same, primarily indicating that the middle is dense and the surrounding is sparse, the east and the west are dense, and the north is sparse. After optimizing the layout, the total area of the permanent basic farmland was found to have only increased by 5.2 hm2, and the rationality of its spatial layout was also greatly improved. The permanent basic farmland in Luoding City was optimized and improved in terms of the amount of arable land, arable land quality, spatial form, ecological environment, and spatial planning. Therefore, this study draws the following conclusions:Evaluating the rationality of arable land plot layout plays a critical role in delineating permanent basic farmland. In the future, the transfer of permanent basic farmland can be carried out according to the layout rationality of the current arable land and basic farmland to effectively promote permanent basic farmland delimitation in Luoding City. Moreover, the rapid optimization method of permanent basic farmland layout in Luoding City based on cultivated land quantity, quality, and ecology also provides a reference value for the permanent basic farmland delimitation of other major grain production areas across the country. |
