In this paper, the characteristics of precipitation, runoff, flood, water quality and other parameters in the Ulungur River Basin, Xinjiang were analyzed by referring to the geographical features and climate characteristics based on the measured data and related documents from the hydrological and meteorological stations in the drainage basin during the period from 1960 to 2010. The results are as follows:① The river was mainly fed by seasonal snow melt water and subsidiarily by the mixed supply of precipitation and seasonal snow melt water in summer, flood occurs generally in spring, especially in early spring, and the proportion of runoff volume in May and June accounted for about 60% of the annual runoff volume;② The drought period was long, the proportion of runoff volume in this period accounted for only about 10% of the annual runoff volume, the proportion of minimum monthly runoff volume accounted for only about 1%, and the difference of annual runoff volume was significant. These were very disadvantageous for hydropower generation and developing local agricultural and pastoral irrigation, and it was suggested to build the water control projects for artificially regulating runoff;③ The silt discharge of the river was low and occurred mainly in flood season from April to June, and its proportion in this season occupied 95% of annual silt discharge;④ The ice period of the river in winter was long, and this was disadvantageous for hydropower generation and constructing water conservancy projects;⑤ The water quality was fine, the ecological environment in the drainage basin, however, was fragile, and it was suggested to enhance the management of water resources and improve the environment in the drainage basin.
