Abstract

The problem of contaminated sites is a hot and difficult issue in global environmental sustainable development. Because the contaminated site carries a large number of harmful substances (heavy metal ions, organic polycyclic aromatic hydrocarbons, toxic gases, etc.), it brings great security risks to the environmental ecological security and people's health. Effective identification of the characteristics of contaminated sites and understanding of the research status and development trend of contaminated sites are of great significance to environmental sustainable development and environmental governance and restoration. Based on Web of Science database, this study systematically, quantitatively and visually analyzes the research status of contaminated sites by bibliometrics and knowledge graph technology. The results show that bibliometrics and knowledge graph are effective in information retrieval and visualization. It can display the information of different scales and different times in the study of contaminated sites, and find the distribution characteristics of popular keywords. The cluster cases of this study show that the problems of contaminated site research mainly focus on suspended particulate matter pollution, water pollution, heavy metal pollution, organic pollution, pollution reduction and bioremediation technology research. In the future, the hot issues of contaminated site remediation and environmental sustainable development will focus on strengthening the research of microbial remediation technology, nanomaterial technology, composite material adsorption technology and so on.
