摘　　要：非粮化耕地治理是实现田块复耕复种的重要措施。科学确定非粮化耕地整治的优先次序及分区对提高非粮化耕地复耕复种治理工程空间布局的合理性具有重要意义。该研究以行政村为评价单元,从立地、耕作和利用状态3个维度建立了非粮化耕地整治适宜性评价模型,以功能管制区内非粮化比率建立了非粮化耕地整治迫切性评价模型,利用四象限分区法,构建了综合整治适宜性和迫切性的非粮化耕地整治分区方法体系,并以陵水县为案例区开展了非粮化耕地整治分区划定和整治策略研究。结果表明:1)恢复耕地用于粮食作物耕作,提高稳定利用耕地规模和质量,满足区域耕地保护任务和保障粮食供给是非粮化耕地整治的核心。2)通过整治适宜性评价筛选出优质耕作地块,利用整治迫切性评价明确整治的优先次序,两者的综合能有效明确复耕复种的工作指向;3)陵水县非粮化耕地整治可分了4个区,即优先整治区、重点整治区、后备整治区和限制整治区,建议基于耕作状态、自然地貌和利用条件的组合差异,制定差别化的非粮化耕地整治策略。研究结果可为编制耕地保护专项规划及引导耕地“进出平衡”空间布局提供科学依据。The cropland can often be converted into non-grain agricultural production,or cropland conversion to non-grain unitization.However,some damage also occurs in the physical and chemical properties of soil,leading to a reduction of the cropland quantity,even threatening the security of the national food supply.Therefore,the consolidation of non-grain cropland for farming can be an important measure to realize the continuing farming of cropland.The consolidation zoning of non-grain cropland for farming is also of great significance to rapidly supplement the farmland resource,and then to improve the quality of farmland fertility and then restore grain production capacity.Taking the administrative village as the evaluation unit,this study aims to improve the scientific and rational zoning of the spatial layout for non-grain field consolidation.A zoning system was also constructed for the non-grain field consolidation integrating the land remediation suitability and urgency.Firstly,nine indicators were selected from the three dimensions of utilization status,site conditions,and tillage conditions.The suitability evaluation model was then constructed for the non-grain field consolidation.Secondly,the urgency evaluation model of non-grain field remediation was constructed using the non-grain ratio of permanent basic farmland,major grain-producing areas,and ecological red line areas.Finally,the suitability and urgency were evaluated on the field consolidation for the four-quadrant spatial zoning.Lingshui County was taken as a case area to carry out the zoning and remediation strategy of non-grain farmland consolidation.The results show that:1)The core target of non-grain farmland consolidation was determined to restore the land for grain crop cultivation.The scale and quality of stable farmland were also improved to fully meet the regional farmland protection tasks and food supply.2)It was much more instructive and reasonable for the four-quadrant remediation zoning scheme to integrate land suitability and urgency.The high
