| Abstract: | In order to reasonably formulate the pollution prevention and control strategy of the Bohai Basin and grasp the environmental pollution status of the basin in time，the temporal and spatial difference analysis of environmental ecological security in the Bohai River Basin based on ecological security was proposed.The environmental pollution in Bohai Basin mainly includes industrial sewage，farmland irrigation，ship pollution and so on.After constructing the analysis sequence and data standardization，the weight of each index was calculated，and the impact of landscape pattern index on ecological security was considered.The landscape area，density，shape and diversity index were used as evaluation factors，and the Pearson correlation coefficient was used to obtain the landscape pattern factors affecting ecological security in different periods.The temporal and spatial differences of environmental ecological security in Bohai Basin were analyzed by using the expression of comprehensive analysis index of ecological security.The results showed that the development trend of ecological security in the basin is steadily increasing in recent years，but there are still serious pollution in Shandong，Liaoning and other areas，which need to be strengthened. |
