Abstract:Taking the Tai'an section of the Yellow River as the research object, this paper focuses on the practice of the River Chief System and the establishment of a long-term mechanism for regional collaborative management. Firstly, it sorts out practical achievements of the River Chief System in Tai'an section of the Yellow River from the aspects of organizational system, river-lake regulation and riparian protection. Secondly, it analyzes prominent challenges restricting the River Chief System and regional collaborative management, such as mismatched agency powers and responsibilities, insufficient holistic thinking, ineffective assessment and incentive mechanisms, low enforcement of laws and regulations, as well as low public participation. Finally, targeted countermeasures for long-term mechanism construction are put forward, including deepening inter-agency coordination, improving scientific assessment, perfecting legal framework for cooperation, encouraging multi-stakeholder participation and strengthening professional talent cultivation, so as to provide references for further implementation of the River Chief System and watershed collaborative management.
