摘　　要：基于1980—2020年中国土地利用数据和社会经济统计面板数据,对耕地非农化与非粮化时空演变特征进行系统分析,揭示其变化规律及驱动机制,以期为耕地可持续利用和稳定粮食安全提供依据。采用标准差椭圆、趋势分析估计综合评估非农化、非粮化动态演变特征,构建非农化、非粮化综合指标体系,构建偏相关模型量化各因子相对贡献。结果表明:(1)时间上,我国非农化形势总体不断趋好,而部分地区非粮化表现出加剧趋势。(2)空间上,东北和中东部地区的非农化问题较为突出,西北、华南以及东南沿海部分地区非粮食生产的比例相对较高。非农化演变存在沿东北-东南方向“极化现象”,非粮化中心呈现出从西南向东北移动的发展态势。(3)经济因素是非农化主导驱动作用,且近10 a来影响程度有所降低。农业生产条件是非粮化的基础因素,同时粮食每亩产值、城乡收入差距等经济因素的推动作用逐渐增加。1980—2020年中国非农化、非粮化时空演变特征与影响因素研究可为科学实施耕地保护决策提供参考。Drawing upon China’s comprehensive land use data and socioeconomic panel statistics spanning 1980-2020,this study meticulously analyzed the spatiotemporal evolution characteristics of nonagricultural and nongrain farmland.It aimed to elucidate their underlying patterns of change and driving mechanisms,establishing a solid foundation for sustainable cultivated land utilization and stable food security.Utilizing the SD ellipse and trend analysis,we comprehensively assessed the dynamic evolution traits of these nontraditional agricultural uses.Furthermore,we constructed a comprehensive index system tailored for nonagricultural and nongrain farmlands and developed a partial correlation model to quantitatively assess the relative contributions of various influencing factors.This comprehensive approach offers a nuanced understanding of the intricate dynamics governing these farmland transitions and their implications for China’s agricultural sustainability and food security.(1)Regarding time,the current situation of nonagriculture farmland in China is getting better,but the nonagriculture phenomenon is still prominent in some areas and tends to intensify further.(2)Regarding space,the degree of nonagriculture is more serious in the northeast,central,and eastern regions,while it is higher in the northwest,south,and some coastal areas of southeast China.The polarization phenomenon exists in the direction of nonagricultural chemical evolution.The nongrain center exhibited a development trend of moving from the southwest to the northeast.(3)Economic factors are the leading driving effect of nonagricultural chemistry,and their degree of influence has decreased in the past ten years.Agricultural production condition is the basic factor of nongrain production,and it is gradually increased by economic factors,such as the output value of grain per acre and the income gap between urban and rural areas.The spatiotemporal evolution characteristics and influencing factors of nonagricultural and nongrain lands in China from 1980
