基于Web of Science数据库的微生物肥料研究发展趋势分析

微生物肥料研究是目前肥料行业的热点领域之一,为了明确该领域在世界范围内的研究现状,通过Web of Science数据库对1900-2018年以来关于微生物肥料的论文进行文献计量分析统计,以探讨该领域的研究现状、研究重点及发展趋势。结果表明:微生物肥料研究从20世纪90年代开始逐渐增长,2003年开始进入全面快速发展时期。以美国、中国、印度、德国和英国等国家的发文量最多;中国科学院、西班牙高等科学研究委员会、法国国家农业研究院、法国国家科学研究院等是主要的发文机构。在研究水平方面表现出欧美等发达国家强于发展中国家的现状,但发展中国家有研究投入不断加大的趋势。在学科分布上主要集中在农学、环境科学及生态学、植物科学及微生物学等学科,在未来表现出以环境科学和农学为主要学科且具有学科交叉的趋势;主要研究主题依然是固氮作用、生物降解与修复和促生长作用等内容,但生物降解与修复、有机质腐熟、改善土壤生态环境和增强作物抗逆性等主题将在未来的研究中成为快速增长的热点领域。上述结果可为微生物肥料学科发展规划和政府管理部门决策的制定提供一定参考。

Analysis on the Development Trends of Microbial Fertilizer Research Based on the Web of Science Database

Microbial fertilizer research is one of the hot fields of fertilizer industry. In order to clarify the current research status of microbial fertilizer field in the world, this paper conducted bibliometric analysis and statistics on the microbial fertilizers papers from 1900 to 2018 through the Web of Science Database to explore the current research status, research focus and development trend of microbial fertilizer field. The results showed that: papers on microbial fertilizer had been increasing gradually since 1990s, and the research on microbial fertilizer stepped into a period of comprehensive development from 2003. The top five countries researching on microbial fertilizer were the United States, China, India, Germany and the UK. The Chinese Academic of Sciences, CSIC, INRA, CNRS, etc. were the main research organizations. The developed countries such as the United States showed the stronger research level than developing countries like China and India, but there was a trend of more devoting to research in developing country. The main subjects on microbial fertilizer contained agriculture, environmental science & ecology, plant science, microbiology and so on. The environmental science and agriculture would be the main subjects with the trend of interdisciplinary research in the future. The main research topic was still on the nitrogen fixation, biodegradation and bioremediation, promoting growth, etc., but biodegradation and bioremediation, decomposed organic matter, improving the soil ecological environment and enhancing the crops resistance would become rapid growthing hot topics in the future research area. These results provided important insights to the development of microbial fertilizer and some reference for decision-making of government.
