“双安全”视阈下我国耕地变化驱动力研究进展与可视化分析

Visual analysis and driving forces of cultivated land change in China under the "Dual Security" vision

将“耕地变化驱动力”研究作为目标领域,从中国知网数据库和外文学术期刊数据库Web of Science(WoS)分别筛选出585篇和296篇文献,利用文献归纳法和CiteSpace对目标领域的中外文献进行对比分析。结果表明:(1)中外文献时间分布大致可分为两个阶段:1999—2010年,中外文献数量分别呈现快速增长状态、缓慢增长状态;2010—2020年,中外文献数量分别呈现波动增长、稳步增长状态。(2)中外文献作者与机构合作联系大多发生在学术机构内部,与其他机构的联系较少;热点研究区域可大致分为快速城镇化区、粮食主产区及生态脆弱区;社会经济因素是最主要的耕地变化驱动因子,而政策因素、自然因素的影响分别在粮食主产区、生态脆弱区的研究中较为多见;外文文献的研究尺度较为均衡,而中文文献中市县尺度研究占据主导位置。(3)中外文献的热点主题大致相同,外文文献在耕地质量、生态变化方面的研究视角更加丰富。最后,本文提出了加强机构合作、丰富耕地变化驱动力研究内涵与对象、拓宽耕地治理目标、充分考虑论文主题与研究尺度匹配性的研究展望。

The target area was "drivers of arable land change",and 585 and 296 papers were conditionally selected from the China Knowledge Network database and the Web of Science database,respectively.We used the literature induction method and CiteSpace tool to compare and analyze the Chinese and foreign literature in the target area.The results show that:(1) the temporal distribution of Chinese and foreign literature can be roughly divided into two stages:from 1999 to 2010,the number of Chinese and foreign literature showed rapid growth and slow growth respectively;from 2010 to 2020,the number of Chinese and foreign literature showed fluctuating growth and steady growth respectively.(2) The authors of Chinese and foreign literature are mostly associated with institutional cooperation within academic institutions,but less with other institutions;the hot research areas can be roughly divided into rapidly urbanizing areas,main grain-producing areas and ecologically fragile areas;socio-economic factors are the main drivers of arable land change,while the influence of policy factors and natural factors are more common in main grain-producing areas and ecologically fragile areas,respectively;the scale of foreign literature is more balanced,while the scale of Chinese literature is more balanced.The scale of research in foreign literature is more balanced,while the city and county scale research dominates in Chinese literature.(3) The hot topics in Chinese and foreign literature are more or less the same,and foreign literature has richer research perspectives on arable land quality and ecological changes.Finally,this paper puts forward the research outlook of strengthening institutional cooperation,enriching the connotation and objects of research on the drivers of farmland change,broadening the objectives of farmland governance,and fully considering the matching of thesis topics and research scales.
