Development Trend of Black Soil Research Based on the Knowledge Map
-
摘要: 分析黑土地研究领域的发展态势,能为我国黑土地保护与保障粮食安全提供情报参考。通过文献计量学和科学知识图谱的方法,对1990—2020年黑土地研究领域的SCI论文进行计量学统计,探讨该领域的研究现状、研究重点和发展趋势。结果表明,全球范围内黑土地研究领域的发文量逐年增长,其中,中国的发文量和H指数居首位,美国和德国发表论文的篇均被引次数高于其他国家,体现了其较高的发文水平。以中国科学院为首的中国研究机构是该研究领域的重要参与者和合作网络中心。发文期刊水平差距较大,论文的总体质量有待提升。黑土地研究领域涉及的学科领域分布广泛,其中土壤科学和环境科学的占比最高,且多学科交叉融合的趋势较明显。黑土地研究经历了从最开始的提高粮食产量,发展为以改善土壤有机质、微生物群落结构、土壤侵蚀等为主题的科学研究。未来应继续加强学科交叉融合,关注土壤质量和健康,落实黑土地保护工作。Abstract: Analyzing the development trend of black soil research could provide information and reference for the protection of black soil and food security in our country. Based on the bibliometrics analysis and scientific knowledge map, the SCI papers in the field of black soil research from 1990 to 2020 were statistically calculated, to discuss the current status, research focus and development trend of this field. The results showed that the number of published papers in the field of black soil research had increased year by year. Among them, the number of papers and H index in China ranked first, and the papers published in USA and Germany were cited more frequently than other countries, reflecting their higher level. Chinese research institutions headed by the Chinese Academy of Sciences were the important participants and cooperative network centers in this research field. There was a large gap in the level of journals, and the overall quality of papers needed to be improved. The field of black soil research covered a wide range of disciplines, in which soil science and environment science accounted for the highest proportion, and the trend of interdisciplinary was obvious. Black soil research had experienced increasing food production from the very beginning, and had developed into scientific research on the theme of improving soil organic matter, microbial community structure, and soil erosion. In the future, it should continue to strengthen interdisciplinary integration and pay attention to soil quality and health to implement black soil protection.
