摘要: 耕地质量状况关系耕地产能与粮食安全问题,耕地质量研究是土地学科研究的重点。利用CiteSpace对1998—2018年的996篇文献进行可视化分析,探讨研究中心词及突现词信息、研究热点及演化趋势,得到当前国内耕地质量研究的知识图谱。结果表明,国内耕地质量研究可划分为4个时段,2007年以后发文量激增,“土地利用与耕地保护”是发文量最多的研究方向;耕地质量研究主题总体上围绕不同时期国家政策开展,当前研究热点是耕地质量“空间差异、补充耕地和时空格局”;耕地质量研究趋势呈现出明显的连通性,耕地综合质量观逐渐被应用于当前研究中。建议今后加强耕地质量基础理论研究,识别出耕地质量关键要素,重视尺度对耕地质量管理的作用。

Abstract: The quality of cultivated land is related to the problem of cultivated land productivity and food security in China. The study of cultivated land quality is an important issue in the study of land discipline. Using CiteSpace to visualize 996 articles from 1998 to 2018, explore the research center words and emerging words information, research hotspots and evolution trends, the knowledge map of current cultivated land quality research is obtained. The results showed that the research on domestic cultivated land quality can be divided into four periods. After 2007, the number of publications increased sharply. “Land use and cultivated land protection” is the most research direction. The subject of cultivated land quality research is generally carried out around national policies in different periods. The current research hotspot is “spatial difference, supplementary cultivated land and space-time pattern” of cultivated land quality; the research trend of cultivated land quality shows obvious connectivity, and the comprehensive quality concept of cultivated land is gradually applied in the current research. It is suggested that the basic theoretical research on cultivated land quality should be strengthened in the future to identify the key elements of cultivated land quality, and the role of scales in the quality management of cultivated land should be paid attention to.
