| Abstract: |
| To comprehensively understand the development characteristics of environmental soil science between 2016 and 2020, the related articles published in Web of Science and China National Knowledge Infrastructure were collected. The research status, development trend and hotspots were analyzed based on analysis tools from Web of Science and bibliometric software CiteSpace. The results indicated that the field of environmental soil science has fruitful achievements and has developed steadily during the study period. China and the United States accounted for more than 50% of international publications. Environmental science journals including, Science of the Total Environment, Environmental Science and Pollution Research and Chemosphere had the most of publications, and soil science journals including, Geoderma, Catena, Plant and Soil and Soil Biology Biochemistry were in the top ten ranks as well. There were 8 important research trends and related hotspots in the field of environmental soil science overseas:microbial community, organic carbon, biochar amendment, N2O emissions, heavy metals, soil erosion, machine learning, and conservation agriculture. The domestic research closely followed international development and focuses on the hotspots including, soil organic matter, nutrients and microorganisms. Lots of efforts had also been paid on soil moisture, biochar, soil erosion and crop yield. |
