After the project of transferring ecological water at the lower reaches of Tarim river in recently years

water flow into Taitema lake

groundwater level along Tarim river rose. Correspondingly

the vegetation health improved in this region. For the purpose of improving environment for a long time at the lower reaches of Tarim river

discuss river improvement

include river dredging and ecological sluices. For the purpose of solving downstream water interception and ecological environment problems in Tarim river basin

it is necessary to implement river dredging project in Daxihaizi reservoir downstream. It have three water conveyance way to choice

through comparing investment

land

construction

management and flood control

select a new built outlet sluice scheme in main dam of Daxihaizi reservoir. The scheme is feasible in economy and technology. According to the principle of vegetation water demand along lower reaches of Tarim river and reasonable ecological sluices number

analyse and protective vegetation area

discuss ecological water transport ways and open order of ecological sluices gate.
