摘　　要：促进耕地集约化利用,是缓解耕地紧缺、确保粮食安全和实现耕地可持续发展的关键。为提高海南岛耕地集约利用水平,推动其热带特色农业高质量发展,基于PSR模型构建耕地集约利用评价指标体系,计算2011—2020年海南岛及各市(县)耕地集约利用度并分析其时空变化特征,结果表明研究期间PSR三个子系统的变化差异性较大,2011—2020年海南岛耕地集约利用水平总体呈下降趋势且在2018—2020年间降低较多,同时,各市(县)耕地集约利用水平大体呈东南沿海高、中西部山区低的空间分布格局,其时空变化则具有西部和南部波动、北部和东部稳定的特点。针对海南岛耕地集约利用的现实状况,提出加强耕地保护、转变耕地利用方式以及进行耕地分区和差异化利用的建议。Promoting the intensive use of arable land is the key to alleviating the shortage of arable land,ensuring food security,and achieving sustainable development of arable land.In order to improve the level of intensive use of arable land in Hainan Island and promote the high-quality development of its tropical characteristic agriculture,this article constructs an evaluation index system for intensive use of arable land based on the PSR model,calculates the intensive use of arable land in Hainan Island and various cities and counties from 2011 to 2020,and analyzes its spatiotemporal change characteristics.The results show that there are significant differences in the changes of the three subsystems of PSR during the research period,From 2011 to 2020,the overall level of intensive utilization of arable land in Hainan Island showed a downward trend,with a significant decrease during2018-2020.At the same time,the level of intensive utilization of arable land in various cities and counties showed a spatial distribution pattern of high in the southeast coast and low in the central and western mountainous areas.Its spatiotemporal changes were characterized by fluctuations in the west and south,and stability in the north and east;In response to the current situation of intensive utilization of farmland in Hainan Island,suggestions are proposed to strengthen farmland protection,transform farmland utilization methods,and carry out farmland zoning and differentiated utilization.
