摘　　要：通过精准把握我国耕地趋粮化的总体态势,深入剖析其空间分布差异性,为保障国家粮食安全和有效缓解耕地非粮化现象提供坚实的科学依据。本文运用空间自相关分析方法探究2006—2022年中国耕地趋粮化的时空演变规律,结果表明:时间维度上,中国耕地趋粮化水平呈现可划分为四个阶段的波动性变化;空间维度上,中国耕地趋粮地区总体由东北部地区向中部地区移动,主要集中在粮食主产区地区,同时,空间集聚具有显著正向相关关系。This paper aims to accurately grasp the overall trend of farmland being used for grain cultivation in China,deeply analyze the differences in its spatial distribution,and provide a solid scientific basis for ensuring national food security and effectively alleviating the phenomenon of non-grain cultivation of farmland.This article uses the spatial auto-correlation analysis method to explore the spatiotemporal evolution law of China's farmland for grain cultivation from 2006 to 2022.The results show that in the,temporal dimension,the level of farmland for grain cultivation in China shows a fluctuating change and is divided into four stages.In the spatial dimension,from an overall perspective,the areas of farmland for grain cultivation in China have moved from the northeastern region to the central region,mainly concentrated in the main grain-producing areas.At the same time,the spatial agglomeration has a significant positive correlation.
