摘要: 在后备资源枯竭,新增耕地开发与生态用地保护冲突严重的背景下,耕地占补平衡制度的持续实施面临重大挑战。提升存量耕地质量,将耕地数量占补平衡转型为耕地产能占补平衡是耕地保护制度创新的选项之一。研究基于政策和技术储备的前瞻性考虑,利用县域农用地分等、土地利用总体规划、第二次全国土地调查更新等国土数据成果及GIS空间分析技术,试图探索构建一套基于质量提升的规划期内县域耕地产能占补平衡潜力评价方法体系,并以平阳县为例,进行应用和检验。结果显示,2011—2020年浙江省平阳县规划建设占用损失的耕地产能为19 227.82 t,通过耕地质量提升可补充的耕地产能为23 104.03 t,耕地产能占补平衡潜力指数为120.16%。这套县域耕地产能占补平衡潜力评价方法体系可为制定和实施耕地产能占补平衡政策提供技术支撑。

Abstract: Due to limited arable land, the conflict between arable land exploitation and ecological land protection is more and more serious. In this context, the requisition-compensation balance of arable land faces significant hurdles. One innovative option to protect arable land is transforming requisition-compensation balance of arable land quantity into requisition-compensation balance of arable land production capacity by improving the quality of arable land. On account of forward-looking consideration of policy and technical reserves, this paper tries to offer a method system for potential evaluation of requisition-compensation balance of arable land production capacity in the planning period based on quality improvement of arable land at county level. The method system built here is based on farmland gradation, general land use planning, and detailed land use survey data, combining with GIS spatial analysis technology. Taking Pingyang County as an example, the applicability of this method system is verified. The study result indicated that: from 2011 to 2020, the production capacity of arable land would lose 19 227.82 t owing to land occupation by construction, and would add 23 104.03 t through arable land consolidation, thus the index number of potential balance of arable land production capacity is 120.16%. Therefore, the method system built in this paper is proved to be well-founded and easy to put into practice,which provides a necessary technological support for formulating and implementing policies on requisition-compensation balance of arable land production capacity.
