Abstract: Keping River located on south slope of the Tianshan Mountains(77°00′～79°05′ E,40°20′～40°55′ N) is a typical rain and spring water supply river,and the most river water come from spring and base flow of the underground water,and annual runoff is very stable,but the emergence of heavy rain caused floods often occur.Hydrological observation of Keping River is only less than a year,but the river is spring water supply,runoff is very stable.According to field investigations and analyzed of Keping River hydrological changes of year 1957,the hydrological feature of Keping River was analyzed.Based on investigation and documentation of historical flood survey to verify the floods in Keping River Basin,the combination of meteorological observation data,studied typical flood events of the last century,and the establishment of a different probability flood in the flood peak flow and the process.The climate warming and precipitation increased in recent decades lead to the strength of the storm flood and increase the frequency.The paper suggested that we should be strengthened the monitoring extreme weather events,and the flood monitoring and building responding measure,specially in agriculture and the safety of reservoirs operation should pay attention to the establishment and strengthening of the measures to deal with climate change.
