摘　　要：以安徽省耕地资源利用变化为研究对象,在分析1989—2018年近30年耕地资源数量和粮食生产变化的基础上,从统计学的角度探寻耕地压力指数变化时空特点及趋势,利用spss25.0软件对耕地压力指数与区域经济发展指标进行皮尔逊相关性分析。结果表明:1989—2018年间,安徽省耕地压力指数时空变化特征显著,总体呈现波动下降态势,粮食生产量的稳步增加保障了区域粮食安全。但是部分地市修正耕地压力指数时空变化趋势差异较大,修正耕地压力指数值一直处于1以上的水平,少部分城市粮食生产不能自给自足。为保障区域粮食安全,围绕城乡融合发展可通过树立耕地保护意识,加快耕地保护体制创新,统筹优化国土空间规划引领与控制,创新保护技术手段,有效提升区域粮食综合生产能力。Based on the analysis of the changes of cultivated land resources and grain production in the last 30 years from 1989 to 2018 in Anhui Province, the temporal and spatial characteristics and trends of the pressure index of cultivated land were studied statistically, SPSS25.0 software was used to analyze the correlation between cultivated land pressure index and regional economic development index by Pearson. The results showed that the pressure index of cultivated land in Anhui Province showed a significant temporal and spatial variation from 1989 to 2018, and the grain production increased steadily, which ensured the regional grain security. But in some cities, the pressure index of revised cultivated land is more than 1, and in a few cities, the grain production can not be self-sufficient. In order to ensure regional food security, the integrated development of urban and rural areas can be guided and controlled by establishing the consciousness of cultivated land protection, speeding up the innovation of cultivated land protection system, and making overall optimization of territorial space planning, innovating protective technical means to effectively enhance regional comprehensive grain production capacity.
