To date, few studies have addressed the ecological risk around brownfield areas in China, and most of these studies have only evaluated the potential harm of the risk source, without considering whether the risk receptor can withstand the ecological risk. Therefore, in order to conduct a more comprehensive ecological risk assessment, this paper added the risk receptor analysis in the ecological risk assessment of the area surrounding a brownfield area and ecological risk assessment of the surrounding areas included both hazard analysis of the risk sources and ecological vulnerability analysis of the risk receptors. In addition, few studies have examined the change of ecological risk over time. Therefore, the present study measured ecological risk at two time points. GIS spatial analysis, which was used to determine spatial differences in ecological, indicated that, before remediation, the Sumen area, Jiuniugang, the Shuiquan area, and Chuanshanlong posed a very strong ecological risk, whereas the Shenjia-Linjia and Changtangzhoujia areas posed a medium risk. The ecological risk was greatly reduced following remediation, and the previously very strong-risk areas were reduced to the strong risk level, whereas the medium-risk areas were reduced to the low risk level. This demonstrated the effectiveness of remediation while there were still some regions, even though only a small part, were in strong-risk levels and they should be strengthened to restore in the future. In the present study, the ecological vulnerability of cultivated land was the largest. It is necessary to further remediate some regions which have the strong vulnerability and large risk to improve the ecological levels.Therefore, areas with large ecological vulnerability and low ecological risk should be targeted for improved monitoring and prevention measures, in order to avoid the occurrence of strong risk.
