Natural water circulation is closely related to artificially water cycle and their hydraulic connection is of great significance to the sustainable use of water resources. Based on the binary water cycle theory of natural - artificial and watershed water balance as a guide, Manas river basin was studied water cycle model (ABMBC), where interaction mechanism in the binary mode was analyzed. Calculation for water cycle flux in the changing environment of Manas river basin was combined with the calculation method for GIS to identify the reasonable proportion flux between natural water circulation flux and artificial cycle flux in Manasi river basin. Water flux analysis for different years combined with different ecological environment and economic development, revealed that the natural and artificial water flux coordination proportion was 33:65. Therefore, in order to maintain and improve Manasi River watershed ecological environment, a volume of approximately 1.0 to 1.4 billion m(3) should be discharged to the watershed downstream each year.
