China’s commitment to maintaining a red line of 1.865 billion mu (approximately 124 million hectares) of arable land is a critical measure to ensure national food security, ecological stability, and sustainable development. This target, established in the National Spatial Planning Outline (2021–2035), mandates that the country must retain at least 1.865 billion mu of farmland by 2035. As the foundation for grain production, the quantity and quality of arable land directly affect food availability for China’s population of 1.4 billion. In recent years, rapid urbanization and industrialization have placed immense pressure on farmland through encroachment, fragmentation, and soil degradation. To counter these challenges, China has implemented strict land-use controls, enforced a balance between land occupied and reclaimed, promoted high-standard farmland construction, and cracked down on the conversion of farmland to non-agricultural or non-grain uses. Advanced technologies such as satellite remote sensing and big data are also being leveraged for real-time monitoring and improved regulatory oversight. Upholding this red line is not only a responsibility to future generations but also a cornerstone for rural revitalization and agricultural modernization.
我国守牢18.65亿亩耕地红线，是保障国家粮食安全、维护生态安全和推动可持续发展的关键举措。这一红线源于《全国国土空间规划纲要（2021—2035年）》，明确到2035年全国耕地保有量不低于18.65亿亩。耕地作为粮食生产的基础资源，其数量和质量直接关系到14亿人口的吃饭问题。近年来，随着城市化、工业化加速推进，耕地面临被占用、碎片化和质量下降等多重压力。为此，国家通过严格用途管制、强化占补平衡、推进高标准农田建设、整治“非粮化”“非农化”等措施，坚决遏制耕地“非粮化”趋势，确保良田粮用。同时，利用卫星遥感、大数据等技术手段加强耕地动态监测，提升监管效能。守牢耕地红线不仅是对子孙后代负责，更是实现乡村振兴和农业现代化的重要基础。
