摘 要：【目的】抚州市地处我国重要粮食主产区江西省赣抚平原，开展抚州市耕地“非粮化”研究对保障粮食安全具有重要意义。【方法】综合利用最新遥感影像技术和土地利用数据将抚州市域范围内种植非粮食作物的耕地图斑以及即可恢复地和工程恢复地作为“非粮化”研究对象，采用核密度分析方法，对抚州市不同类型“非粮化”地块的空间分布特征及其景观格局进行了分析探讨。【结果】1）抚州市耕地“非粮化”面积共计104 202.11 hm2 ，以种植非粮食作物的耕地和工程恢复地这两种类型为主。2）抚州市的“非粮化”耕地集中分布在抚州市北部平原地区和南部的生态农产品特色生产区，主要是由于当地的特色产业发展和农业结构调整以及城镇化和工业化的发展。3）对景观格局指数进行分析可得出，在景观格局分布规模方面：工程恢复地>种植非粮食作物耕地>未耕种耕地>即可恢复地。【结论】建立健全“非粮化”管控制度，严格管控耕地“非粮化”行为；加大政策宣传与种植粮食补贴的资金投入，以保障粮食安全。

Abstract: [Objective] Fuzhou City is located in the Ganfu Plain of Jiangxi Province, an important grain producing area in China. Conducting research on the “non-food” of cultivated land in Fuzhou City is of great practical significance for ensuring food security. [Method] By comprehensively utilizing the latest remote sensing images technology and land use data, the cultivated land patches, recoverable land, and engineering restoration land planted with non food crops within the scope of Fuzhou city were selected as the research objects of “non-food”. The spatial distribution characteristics and landscape patterns of different types of “non-food” plots in Fuzhou city were analyzed and discussed using kernel density analysis method. [Result] 1) The total area of “non-food” cultivated land in Fuzhou City is 104 202.11 hm2 , mainly consisting of cultivated land for “non-food” crops and engineering restoration land. 2) The non grain cultivated land in Fuzhou City is concentrated in the northern plain area and the southern ecological agricultural product production area, mainly due to the development of local characteristic industries and the adjustment of agricultural structure, as well as the development of urbanization and industrialization. 3) By analyzing the landscape pattern index, it can be concluded that in terms of the distribution scale of landscape patterns, engineering restoration land>cultivated non food crop land>uncultivated land>recoverable land. [Conclusion] Establish and improve the “non-food” control system, strictly control the “non-food” behavior of cultivated land; Increase investment in policy promotion and subsidies for grain cultivation to ensure food security.
