For more scientific and rational use of water resources in the basin of arid areas, best water resources development mode need to be determined for different areas of the basin. Typical arid areas basin - the Manas River Basin is taken as an example, on the basis of building the evaluation system of rational development of water resources and determining the weight vector of each index, by using of fuzzy comprehensive evaluation method, best development mode of regional water resources in the basin is determined, on this basis, the scientific and rational development mode of arid area water resources is summed up. The upper piedmont alluvial fan is mainly to be the development of surface water, the development of surface water-based, supplemented by groundwater or joint development of surface water and groundwater is mainly mode in the overflow zone of the fan edge, alluvial plains mainly develops groundwater-based, supplemented by surface water, the oil industry demands water in some areas, so the measurement of appropriate exploitation of groundwater can be taken in some part areas rich in groundwater.
