(1) Background: Identifying ecological security patterns and restoring the Beijing-Hangzhou Grand Canal in Shandong is vital for future ecological conservation and maintaining ecosystem sustainability. (2) Methods: The study area was selected, and the InVEST3.9.0 model was used to assess natural-environment ecosystem services. An optimal evaluation approach based on the Minimum Cumulative Resistance model was developed to define the ecological security pattern. (3) Results: There were 20 ecological source areas in the lower and east portions of the study area, mainly grasslands, forests, and water areas. Additionally, 40 ecological corridors, 48 ecological pinch points, and 75 ecological barrier points were generated, densely distributed in the east. The area was divided into five core functional zones. (4) Conclusions: Establishing ecological function zones and considering landscape changes from high-frequency human activities in spatial planning can lead to a more reasonable division of ecological restoration areas. Ecological function zone construction can enhance understanding of implementing ecological security patterns in national land planning and support national ecological security goals.
