现阶段大规模的耕地撂荒成为威胁国家粮食安全的不安因素。国家耕地撂荒治理工作的目标要求是统筹利用撂荒耕地，激发多元主体力量参与耕地撂荒治理，实现耕地撂荒治理的可持续性。目前耕地撂荒治理中存在三个问题：撂荒耕地统筹利用状况不理想，多元主体力量未得到有效激发，耕地撂荒治理缺乏可持续性等。基于政策协同视角，从纵向、横向、时空三个维度剖析当前耕地撂荒治理问题的成因并提出对策：完善政策举措，使撂荒治理政策更好贯彻撂荒耕地利用目标；加强主体协同，发挥撂荒治理多元主体作用；优化治理方案，增强撂荒治理方案的施策成效，提升方案的可持续性。

At present, the large-scale abandonment of arable land has emerged as a potential threat to national food security. National goals and requirements for the rectification of abandoned land are: coordinate the utilization of abandoned farmland, stimu-late the participation of multiple stakeholders in farmland abandonment management, and achieve the sustainability of farm-land abandonment management. Three issues in the current governance of abandoned arable land are summarized based on these targets and requirements: suboptimal overall utilization of abandoned arable land, ineffective mobilization of diverse stakeholders and lack of sustainability in the governance of abandoned arable land. Based on the perspective of policy syn-ergy, this paper analyzes the causes of the current problems in the governance of abandoned arable land from vertical, hori-zontal, and spatiotemporal dimensions. Finally, based on the reasons behind the identified problems, three countermeasures and suggestions are proposed: firstly, refine policy measures to better align with the objectives of abandoned arable land uti-lization through enhanced implementation of abandoned arable land management policies; secondly, strengthen collaborative efforts among stakeholders and give full play to the role of multiple stakeholders in abandoned land management; thirdly, optimize governance plans, enhancing the effectiveness of abandoned arable land management plans and promoting their sustainability.
