| 摘要: |
| 【目的】系统分析国内外土壤溶质运移领域的研究现状，探究其研究热点与未来发展趋势。【方法】基于Web of Science核心数据库（WoS）和中国知网数据库（CNKI），借助CiteSpace和VOSviewer可视化软件，从发文数量、发文国家、发文机构、文献来源、学科分布和关键词着手，对2003—2022年国内外土壤溶质运移研究进行可视化分析。【结果】①国内外土壤溶质运移研究总体呈上升趋势，且英文的发文数量多于中文。其中，中国和美国在该领域占据主导地位。②在发文量前10的机构中，中国仅有中国科学院，美国则有4家。此外，国内机构间的合作较为松散，而全球相关机构间的国际合作较为紧密。③该领域刊出的主要英文期刊有《Journal of Hydrology》《Vadose Zone Journal》《Water Resources Research》，主要中文期刊则为《灌溉排水学报》《水土保持学报》《节水灌溉》。④土壤溶质运移研究主要聚焦环境科学、水资源学和农业学等学科领域，且各学科间的知识内容具有交互性。⑤国内在该领域研究的主要关键词为“重金属”、“水盐运移”和“重金属迁移”，国外则为“solute transport”、“transport”和“water”。【结论】土壤溶质运移仍然是未来的研究热点，今后可从以下几点入手：生态系统中重金属或污染物的迁移转化；土壤溶质运移的尺度效应；农田灌排和耕作模式下的生态环境效应；考虑多因素影响的土壤溶质运移和作物生长耦合模型建立；土壤改良剂的筛选和集成应用示范。 |

| Abstract: |
| 【Objective】This study aims to systematically analyze the current research and development in solute transport in soils and elucidate the research hotspots and its future development.【Method】The analysis is based on papers collected by the Web of Science (WoS) and the China National Knowledge Infrastructure (CNKI) database, with the help of CiteSpace and VOSviewer visualization software. The knowledge mapping analysis of soil solute transport research topics was conducted based on the number of publications, countries of contributions, institutions of contributions, literature sources, subject distribution and keywords.【Result】①Soil solute transport research has been in increase and the number of publications in English is higher than that in Chinese. Among them, China and the United States published much more than other countries. ②Among the top 10 institutions that published most, there is one from China (University of Chinese Academy of Sciences) and four from United States. There is less cooperation between Chinese scientists than their peers in other countries. ③The main English journals publishing more papers in this field are ‘Journal of Hydrology’, ‘Vadose Zone Journal’ and ‘Water Resources Research’, while the Chinese journals are ‘Journal of Irrigation and Drainage’, ‘Journal of Soil and Water Conservation’ and ‘Water Saving Irrigation’. ④Soil solute transport research is mainly in environmental science, water resources and agriculture, and the knowledge content of each discipline is interactive. ⑤The main keywords in papers published by Chinse scientists are “heavy metals”, “water-salt transport” and “heavy metal transport”, while for others the keywords are “solute transport”, “transport” and “water”.【Conclusion】Soil solute transport research is still a hotspot, and future research is likely to focus on transport and transformation of heavy metals and other pollutants in ecosystems, scaling up the effect of soil solute transport to large scale, ecological and environmental effects of irrigation and drainage, as well as tillage, coupled modeling of soil solute transport and crop growth considering the influence of multiple factors, and the consequence of soil conditioner applications. |
