摘 要:结合最小人均耕地面积构建了2010—2020年安徽省的耕地压力指数模型,并利用ArcGIS软件分析了安徽省16个地级市耕地压力指数的时空变化规律,结果表明:2010—2020年安徽省耕地压力指数总体呈波动下降的趋势,无明显耕地压力;耕地压力区域性差异明显,皖北地区处于无压力区,且耕地压力指数呈不断下降趋势,耕地压力明显区主要分布在皖南山区和人口密度、经济发展迅速的地区,且耕地压力指数呈上升趋势;2020年合肥市进入低压力区,黄山市的耕地压力指数一直大于1.5,其耕地承受着较大的压力。综上,提出了降低安徽省耕地压力指数的建议,以期为安徽省耕地保护和综合生产能力的提高、保障粮食安全等政策的制定提供参考。In this paper,the cultivated land pressure index model was established based on the minimum per capita cultivated land area,and the spatiotemporal variation of cultivated land pressure index in 16 prefecture-level cities in Anhui Province was analyzed by ArcGIS software during 2010~2020.The results showed that the cultivated land pressure index of Anhui Province showed a fluctuation downward trend from 2010 to 2020,and there was no obvious cultivated land pressure.The regional difference of cultivated land pressure was obvious,and the pressure index of cultivated land in northern Anhui was in the no-pressure region.The cultivated land pressure index showed a decreasing trend.The cultivated land pressure areas were mainly distributed in the mountainous areas of southern Anhui and the areas with rapid population density and economic development,and the cultivated land pressure index showed an increasing trend.In 2020,Hefei entered the low pressure area,and the cultivated land pressure index of Huangshan was always greater than 1.5,and the cultivated land was under a long pressure.Based on this,the suggestion of reducing the cultivated land pressure index in Anhui province was put forward,in order to provide reference for the policy making of cultivated land protection,improvement of comprehensive production capacity and guarantee of food security.
