摘要:

土壤是人类赖以生存和社会发展的重要基础资源,是自然生态系统中的重要组成部分。对土壤养分以及土壤生物的相关研究具有重要的理论基础意义,相关研究也越来越多,但缺少系统的文献梳理,对研究领域的发展趋势及热点演变特征认识不足。基于文献计量学软件CiteSpace及CNKI数据库的文献数据,对文献的发文量、作者群、发文机构、关键词及突现等进行聚类可视化分析。结果表明,从2001年开始发表以土壤养分与土壤动物相关关系为研究对象的论文,且发文量随时间推移每年均有所增加,至2016年该研究领域的论文发文量保持相对稳定。研究机构以高校为主,主要包括南京农业大学、中国科学院大学、中国农业大学和中国科学院南京土壤研究所等;近20年的土壤养分-蚯蚓研究中土壤质量和群落结构这2个关键词是2001—2021年最具有突发性的研究热点,从2020年开始对土壤健康的研究是一个新方向。

Abstract:

Soil is an important basic resource for human survival and social development, and is an important component of natural ecosystem. The research on soil nutrients and soil biology has theoretical significance. Although there are more and more related studies, the systematic literature review is lacking and the understanding of the development trend and hotspot evolution characteristics of the research field is insufficient. In this paper, based on literature data of CNKI database, we conducted cluster visualization analysis on the number of publications, author groups, publication institutions, keywords and emergence of literature by the CiteSpace, a bibliometrics software. The results show that the number of papers published on the relationship between soil nutrients and soil fauna has increased each year since 2001, and has remained relatively stable since 2016. Research institutions in China are mainly colleges and universities, such as Nanjing Agricultural University, University of Chinese Academy of Sciences and China Agricultural University, and Nanjing Soil Institute of Chinese Academy of Sciences is also a main research group in this field. Soil quality and community structure were the two most prominent research hotspots in soil nutrient-earthworm research in 2001-2021, and the research on soil health has been a new trend since 2020.
