For the Tarim River

the conception of "guarantee ecological water first" and "water resource is severely restricted" must be embodied. The Tarim River Water Resources Redistribution Project (TRWRP) should be entered on guaranteeing ecological water. The goal of the project should be oriented towards insuring ecological water in the near future. The goal means both longitudinal and transverse balances in space. Based on controlling the total amount

the various purposes of water

especially

the ecological water should be controlled

this is called structure control. Ecological water quotas are both basic and limit binding. The water quota of the river's section is a concept of both total amount and structure control. The quotas for a section are an integrated system of combing horizon with longitudinal

quality control with structural control and ecological guarantee with productive guarantee instead of neither only one or totally one.Process control is necessary and another feature of Tarim River water redistribution. In a nearly future

process control should firstly realize apportionment in a natural year

the yearly apportionment principle is: based on the nature incoming water

the quota of a section should be increased when the incoming flow is abundant and decreased when short according to the relative proportion of release and incoming flow for many years.
