摘　　要：耕地保护指标是空间规划中约束耕地规模底线的核心政策工具。以2006—2020年省级土地利用总体规划为例,运用粮食分区视角和多层线性模型等方法,探究市级行政单元耕地保有量指标的空间分配格局和影响因素。结果表明:(1)耕地保有量指标分配存在西北集聚、东南均衡的空间格局,“倒挂型”指标在总量指标要求下实现区域间分配调度。(2)耕地资源和机械设施更丰富的市级单元承担更多耕地保护任务,经济水平更高和开发投资更多的地区则相反。(3)粮食主产区更倾向农业规模化生产和约束建设用地的分配导向,粮食主销区更倾向机械化生产的耕地集约分配导向。同时,结合国土空间规划体系对耕地指标分配策略的调整优化提出差异化的建议。The area of cultivated land reserved is a core policy tool to constrain the bottom line of cultivated land scale in spatial planning.Taking the 2006-2020 provincial overall plans for land utilization as example,this study explores the spatial distribution pattern and influencing factors of the area of cultivated land reserved in prefecture-level administrative units,using the food zoning perspective and hierarchical linear model.The results show that:(1)The area of cultivated land reserved shows a spatial pattern of concentrated in the northwest and balanced in the southeast,and the"cap lower than existing amount"quotas are distributed among regions under the requirement of the total quotas.(2)Prefecture-level administrative units with richer cultivated land resources and mechanical facilities undertake more tasks of cultivated land protection,while units with higher economic levels and more development investment do the opposite.(3)The main grain-producing regions are more inclined to the allocation orientation of large-scale agricultural production and constraint of construction land,while the main grain-marketing regions are more inclined to the allocation orientation of cultivated land intensification with mechanized production.Finally,this study proposes differentiated suggestions for the adjustment and optimization of cultivated land allocation strategies in the context of the territorial spatial planning system.
