Abstract：To enhance the accuracy and eficiency of spatiotemporal dynamics monitoring in typical bay areas，this study evaluates the applicability of multi一source remote sensing imagery in discriminating typical marine functional zones，such as port operation zones，intertidal buffer areas，and marine aquaculture zones，and using Jiaozhou Bay as the study area， this research integrates multi-source remote sensing data （Sentinel -1 ，Sentinel-2，and MODIS），employs a CNN-RF hybrid algorithm，achieving an overall classification accuracy of 91.68% and a Kappa coeficient of O.869. These results significantly surpass those of traditional SVM methods （81.35% ，0.756） and multi-scale segmentation approaches （ 85.92% ，0.802），thereby validating the superior performance of multi一 source remote sensing fusion and inteligent algorithms in interpreting complex marine environments.
