Research on Heightening Water Use Rate on River Basin Scale in Chinese InlandExperiment and demonstration of water-ecology-economy management in the Heieh river basin

Water resource is one of the most important factors in human survival and social development. The ecological problem that limits the sustainable development of Chinese inland river basin, originates from the inharmony between low water resources capacity and high population presurre. The study summarized partly recent achievements of experiment and research on water source conservation, water use rate improvement on river basin scale as well as water resource distribution in the water-ecology-economy system of Heihe river basin. It has revealed the feasibility and potential in improving water use rate on the basine scale with practical example. To strengthen basic study, to introduce innovation such as virtual water and to combine between experts and managers are going to further increase water use rate on basin scale.
