摘要: [目的/意义] 土壤微生物是土壤最活跃的组成,关乎土壤生态系统的健康。因此摸清土壤微生物研究领域的热点、前沿及趋势,有助于科研人员把握选题内容及方向。[方法/过程] 以CNKI中国学术期刊收录的2010年至2019年土壤微生物的核心期刊文献为分析对象,应用CiteSpace V软件分析发文作者、机构及期刊的分布特点,并绘制关键词共现、突现词分布及关键词突现术语时线图的知识图谱。[结果/结论] 每年中国土壤微生物相关文献量均达到400篇以上,该领域研究持续保持较高热度。以西北农林科技大学和中国科学院大学为核心的重点研究单位,以沈其荣、杨殿林、毛志泉为核心的三大作者群,为该领域发展做出了突出贡献。研究热点随时间推进有所演变,统分为四大模块:第一,间接反映土壤微生物的指标(土壤酶活性,土壤呼吸,土壤微生物量碳、氮);第二,研究方法的成熟发展(磷脂脂肪酸、变性梯度凝胶电泳、Biolog-ECO技术、高通量测序);第三,土壤微生物的直观表征(微生物群落结构及功能多样性);第四,影响因素的探究(土壤类型及土地利用方式、施肥、农作物、氮沉降、生物炭)。高通量测序等分子生物学方法及系统生物学方法的应用、生物炭开发利用和氮沉降影响及改良措施研究作为前沿应被持续关注和深入探讨。

Abstract: [Purpose/Significance] Soil microorganism is the most active component of soil, which is the key factor of a healthy soil ecosystem Therefore, to investigate the hotspots, frontiers and directions of soil microorganism research is helpful for researchers to understand research topics and directions. [Method/Process] Using CiteSpace V software papers of soil microbiology published by key journals from 2010 to 2019 collected by CNKI were used to analyze the distribution characteristics of authors, institutions and journals, and to draw the knowledge graph of keyword co-occurrence, burst terms distribution and the time line map of keyword burst terms. [Results/Conclusions] There are more than 400 articles about soil microorganism area published in China every year, and the research in this field continues to draw attention. Northwest A&F University and University of Chinese Academy of Sciences are the key research institutions, and Shen Qirong, Yang Dianlin and Mao Zhiquan are the core author groups, which have made outstanding contributions to the development of this field. The research hotspots have evolved over time, and can be divided into four modules: First, indirect indicators of soil microorganisms (soil enzyme activity, soil uptake, soil microbial biomass carbon and nitrogen); second, mature development of research methods (Phospholipid-derived Fatty Acids, denaturing gradient Gel electrophoresis, Biolog-ECO technique, and high throughput sequencing); third, the visual representation of soil microorganisms (microbial community structure and functional diversity); Lastly, the impact of factors (soil type and land use, fertilization, crops, nitrogen deposition, and bio-char). The application of molecular biological methods such as high throughput sequencing and system biological methods, the development and utilization of bio-char, the influence of nitrogen deposition and the improvement measures should be paid more attention as the focus of future research.

Key words: soil microorganism, CiteSpace, research hotspots, frontier trends
