上述负责人介绍，自2024年以来，省自然资源厅实施"百亩方、千亩方、万亩方"耕地集中连片整治，通 过连续开展了两批耕地集中连片整治试点工作，支持珠海市、中山市、广州市南沙区、佛山市南海区、 河源市东源县、韶关市南雄市、茂名市高州市、河源市龙川县和梅州市蕉岭县结合全域土地综合整治、 高标准农田建设等工作，合力推进耕地和永久基本农田集中连片保护，推动"良田比较集中"，为积极探 索耕地保护新路子。随着广东各地深入推进《广东省耕地保护专项规划（2021—2035年）》落地，不少 地区关于耕地集中连片整治的探索步伐已经迈出，"林耕置换""多田套合""小田变大田"等实施路径不断 涌现。 第35个全国"土地日"的主题为"节约集约用地 严守耕地红线"。6月25日，广东省纪念第35个全国土地日 主题宣传活动在广州举办。活动现场，省自然资源厅有关负责人介绍，广东已连续25年实现耕地占补平 衡，连续4年实现耕地净增加，以仅占全国1.9%的土地面积，承载起全国8.9%的人口和10.9%的经济总 量，为广东"百千万工程"实现"三年初见成效"提供强大支撑，更为筑牢国家粮食安全根基贡献力量。 近年来，广东全面推行"田长制"，创新构建耕地保 ...

Core Viewpoint - The article emphasizes the importance of land conservation, particularly arable land, in ensuring national food security, highlighting the need for a robust system to protect and utilize land efficiently [1][2]. Group 1: Current Status of Arable Land - As of 2023, China's arable land area is reported to be 1.929 billion acres, with a shift from a trend of "decrease in the south and increase in the north" to "increase in both south and north," resulting in a net increase of 2.105 million acres in southern regions [1]. - The area of sloped arable land (over 25 degrees) has decreased by 1.3219 million acres, while flat arable land (under 2 degrees) has increased by 7.147 million acres [1]. Group 2: Challenges in Arable Land Protection - The country still faces challenges such as low per capita arable land, poor quality of arable land, and insufficient backup resources, with issues of "non-agriculturalization" and "non-grainization" of arable land remaining prominent [2]. - Problems like farmland abandonment, soil erosion, groundwater over-extraction, soil degradation, and increased agricultural pollution are prevalent, indicating that the foundation for protecting arable land is not solid [2]. Group 3: Policy and Institutional Framework - There is a need to enhance the arable land protection system, focusing on quantity, quality, and ecological balance, with responsibilities clearly defined for provincial and local governments [3]. - The "National Land Spatial Planning Outline (2021-2035)" has been completed, setting clear tasks for the protection of arable land and permanent basic farmland [3]. Group 4: Strategies for Improvement - The article suggests reforms in the balance of arable land occupation and compensation, integrating various land use activities into a unified management system [3]. - Efforts are being made to improve arable land quality, with plans to convert all permanent basic farmland into high-standard farmland and establish a management mechanism to optimize land layout [3]. Group 5: Economic Incentives - To combat the issues of "non-agriculturalization" and "non-grainization," it is crucial to enhance the income security mechanism for grain farmers and promote modern, intensive agricultural practices [4]. - Establishing a compensation mechanism for major grain-producing areas is essential to create a collaborative effort in arable land protection [4].
