Bibliometric analysis of soil Cadmium pollution research based on CNKI database
Using the CNKI database from 2002 to 2021 as a sample,the data exploring and quantita-tive analysis of soil cadmium pollution research literature were conducted using CiteSpace literature visualization software.With the help of statistical and bibliometric knowledge,the number of publica-tions,main publishing institutions,authors,journals,and keyword situations related to domestic soil cadmium pollution research literature were statistically analyzed and depicted.The study investigated the research hot spots and development trends in soil cadmium pollution over the past 20 years.The results show that soil cadmium pollution research in China has gone through three main stages:bud-ding,steady rise,and rapid increase.The journal with the most publications is the Journal of Agro-Environment Science,and the representative scholar in this field is Xu Yingming from the Environ-mental Monitoring Institute of the Ministry of Agriculture and Rural Affairs.The institution with the highest publication output is the Environmental Monitoring Institute of the Ministry of Agriculture and Rural Affairs.Currently,the research hot spots mainly focus on the migration and transformation of cadmium,passivator,and the remediation of cadmium-contaminated soil.This study contributes to understanding the current status and progress of domestic soil cadmium pollution research,providing references for future research and applications.
