This study aims to establish a four-dimensional nurturing model tailored for the cultivation of applied innovative talents within the inland waterway ship and ocean engineering majors. By conducting a thorough analysis of the current state of professional talent cultivation and identifying the principal challenges, the study delineates the theoretical underpinnings and constituent elements of the four-dimensional nurturing model. Furthermore, it investigates the model's application in the construction of curricular systems, the reform of practical teaching, the cultivation of innovative capabilities, and the enhancement of humanistic qualities. The research employs case analysis to empirically test the effectiveness of the model and devises an evaluation index system to assess its outcomes. Results indicate that the four-dimensional nurturing model significantly enhances students' comprehensive abilities, offering fresh perspectives and methodologies for professional talent development. Lastly, the study proposes recommendations for policy formulation and future research directions.
