Influenced by human activities and social economic development, some rivers in Hubei Province are suffering from water shortage, water environment deterioration and water ecological degradation, which have seriously threatened the sustainable development of human life and social economy. A typical river in Hubei Province is select as the research object and the river ecological water requirement is calculated based on the velocity method and environmental flow index factors are considered. The results of the velocity method and the Tennant method are considered synthetically to determine the ecological water requirement under comprehensive conditions. The conclusion provides technical support and reference for the improvement of river ecological environment.
Key words
