基于CiteSpace科学计量学分析土壤镉污染研究进展与趋势

镉污染的治理是维持土壤可持续发展、保障人体健康和自然环境的重要举措。通过对国内及国际土壤镉污染领域研究脉络和趋势探讨的分析，从而为镉污染土壤研究人员明确当前研究领域的前沿和新趋势提供了有价值的信息。使用CiteSpace对与“镉污染土壤”相关的知网1 100篇文献及Web of Science 4 698篇文献分别进行知识图谱的绘制及可视化分析。国内镉污染土壤经历了萌芽起步和平稳上升2个主要阶段，而国际经历了萌芽起步和井喷上升2个主要阶段；我国在该领域研究的代表性学者为四川农业大学的林立金且发文量最多的机构为四川农业大学；我国与澳大利亚、意大利、美国等国家存在镉污染土壤领域的研究合作关系；国内外有关镉污染土壤研究领域主要分为镉污染土壤健康风险分析、镉污染土壤环境特征和镉污染土壤环境修复3个子领域。研究结果表明，中国在镉污染土壤的研究中是最突出的国家，占发文总量的34.8%,最可能的原因是，与其他国家相比，中国政府和研究机构的资助支持政策更为果断。该研究有助于研究者发现新的研究前沿，区分基于镉污染土壤知识最关键的子领域并为从事相关领域研究的学者在未来进行多元化扩展提供了有利的参考信息。目...

Advance of Research and Trend in Soil Cadmium Pollution Analysis Based on CiteSpace Scientometrics

Cadmium pollution control is an important measure to maintain soil sustainable development, protect human health and natural environment. Through the analysis of the research context and trends in the field of soil cadmium pollution at home and abroad, the valuable information for researchers to clarify the frontier and trends in this field was provided . CiteSpace was used to draw and visualize the knowledge map of 1100 CNKI literatures and 4698 Web of Science literatures related to '' Cd-contaminated soil ''. The domestic cadmium-contaminated soil has gone through stages of startup and stable rising, however, it has experienced two main stages of sprouting and blowouts in western countries, Lin Lijin from Sichuan Agricultural University is a representative scholar in China in this field, who has published the most of the papers about it. Sichuan Agricultural University has established cooperation with Australia, Italy, the United States.etc.in the field of cadmium-contaminated soil; The research of cadmium-contaminated soil are mainly divided into health risk analysis of cadmium-contaminated soil, environmental characteristics of cadmium-contaminated soil,and three sub-fields in environmental remediation of cadmium-contaminated soil.The results showed that China is the most prominent country in the research of cadmium-contaminated soil, accounting for 34.8% of publications. Compared with foreign countries, the Chinese government and research institutions have make more decisive support policies. This study helps researchers discover new research fronts, distinguish the most critical sub-fields based on cadmium-contaminated soil knowledge, and provide references for scholars to diversify and expand this research in the future. Therefore, in the cadmium-contaminated soil research, emphasis should be placed on cross-background, cross-institution, cross-border cooperation and cross-discipline. The role of cadmium-contaminated soil is conducive to mutual learning between different teams, thereby accelerating the pace of great leap and diversified development in the field of cadmium-contaminated soil.
