major problems of the Weihe River have been summarized. The had been given to domestic, production and eco-environmental
ecological basic flow of Baoji section, Weihe River has been water uses in the allocation of water resources. The eco-
estimated through Tennant method, 90% flow duration method and environmental water needs in rivers has set by exposing the
minimum monthly average flow method. It has been concluded that relationship between water resources and eco-system.
the ecological basic flow of Baoji section is 10 m3/s. On the actual
condition, the ecological basic flow guarantee measures are
