The particular natural condition and improper human activities result in the vast consumption of deregulated river water. The consumption arisen from natural factors takes up a considerable percentage in the total amounts of both resources and water consumption

which are mainly due to natural evaporation

uneven distribution of run off seasons; frequent changes of river course

suggestting man's lower level and capability in controlling the river. Improper human activities are another significant factor for the loss of water resources

typified by the deregulation of management over application. The deregulation of application in water resources on the other hand

grows out of man's low capability and level in controlling rivers. The key to improving the efficiency and level in water resources application lies in that we must enhance scientific regulation and efficient effect. The engineering control is a basic measure to enhance control force and also basis on which we execute management on law

price management

planning administration and water conservation. It is the key and strategical thought in solving the problems about the river. In the course of western China's development

we mustn't miss the grand opportunity for eco environmental construction stressed by the state and carry out the construction on the overall control works of the Tarim River.
