This study in Binzhou city of Shandong Province classified land use types by using remote sensing image data for 2000, 2005, 2010 and 2015, with a grid re-sampling size of 3km×3km in the study area. The ecosystem service value and ecological risk index were calculated and evaluated, and their dynamic changes and spatiotemporal correlations were analysed. The results showed that, (1) from 2000 to 2015, the total value of ecosystem services in Binzhou City continued to increase from 168.06×10⁸ yuan to 205.30×10⁸ yuan, and the ecological risk index showed a slowly decreasing trend, with an overall decline of 5.86%. Therefore, regional ecological security had improved, (2) the ecosystem service value per unit area and the ecological risk index were strongly positively correlated although with some positive spatial correlation and (3) the change of ecosystem service value lagged behind the ecological risk index to a certain extent, and there was a strong possibility of reducing the change of ecosystem service value in high-level ecological risk areas. This study will help to provide a baseline reference for the construction of regional ecological security patterns and the formulation of environmental protection policies.
