Abstract
Taking the China Academic Journal Network Publishing Database as a platform, we constructed a co-word matrix with the high-frequency keywords of ecological/environmental risk related papers published on core journals. We made multidimensional scaling analysis and cluster analysis using SPSS, and discussed the status of ecological risk related research. The results show that the research hotspots can be divided into five aspects, including ecological risk assessment on heavy metals in the bottom mud, ecological risk assessment of toxic organic pollutants, regional landscape ecological risk, environmental safety accidents and risk management, and other types of ecological risk such as transgenic and biological invasion.
