| الوصف: | Water use of the ecosystem in the Wei River has been greatly reduced because of fierce competition between social–economic and eco-environmental water use, which leads to serious eco-environmental issues. Stakeholder theory was applied to the water resources utilization, and an improved holistic method for determining the eco-environmental flow was proposed. Considering the principles of inflow of tributaries, water intake from key sections, water balance and eco-environmental function regionalization, the new method integrated several methods to determine the water demand for the sub-items of eco-environmental flow. The three-level management targets of eco-environmental flow were proposed based on the opinions of stakeholders. Taking Shaanxi Section of the Wei River as an example, the eco-environmental flow at different levels was given for five key sections. The results show that: (1) the improved holistic method integrates multiple methods and models, making the calculation results of eco-environmental flow more scientific and reasonable; (2) the three-level management targets of eco-environmental flow can adapt to development and change in practical applications, and are operable and dynamic; (3) as a representative of the public benefits of ecosystems, government participates in the discussion of stakeholders and better coordinates competition among stakeholders. The improved method provides a new idea and reference for comprehensively and scientifically promoting reservoir ecological regulation. HIGHLIGHTS The improved holistic method combines various methods and models to make up for the limitation of a single method.; The three-level management targets of eco-environmental flow are operable and dynamic.; The government represents the public benefit of the ecosystem and better coordinates water use competition among stakeholders.; |
