Ecological Operation in the Tarim River Basin Based on Rational Allocation of Water Resources

Based on the authorized projects of water resources allocation and the practices of the ecological water conveyance in the past 10years,we discussed the relationship between ecological water conveyance and rational water resources allocation, and analyzed the key issues of ecological operation and the basic framework of ecological operation in the Tarim River basin.The environmental flows in Alar Station were calculated. We discussed the goals and measures of ecological operation in the Tarim River basin and suggest some regulations of ecological operation,such as combination of synchronous with concentration in the headstream, water consumption control by subsections in the Tarim River and underground water level regulation in lower reaches of the Tarim River.The regulations are expected to be useful in the integrated water resources management,the operations of the hydraulic engineering and the protection of ecological environment in the Tarim River basin.
