Allocation of Water Resources and Environment Management of the Bachuan River in Chongqing Based on Ecological Water Requirement

Abstract:

The Bachuan River is the main water source for urban life and industrial and agricultural production of one county in Chongqing, China, but water shortage is serious due to the water pollution and low development rate at present. In this paper, water resources quantity and quality of the Bachuan River basin were analyzed, and the water demand and supply were calculated. The results indicate that for the polluted river, in addition to the living and production water requirements, the guarantee of ecological water is important for the environment improvement. Reasonable joint regulation of upstream reservoirs is needed to maintain the water supply of living, production and ecological maintenance, and the water resources allocation should be adjusted according to the water inflow in different seasons. At the same time, water environment treatment and water conservation are also necessary to help to improve the water quality, and water transfer projects can be considered if the flow is too small in dry season.
