| 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. |
