El Nino and La Nina are the events concerned internationally. The correspondingrelationship between El Nino events, temperature, precipitation and runoff in the Qilian mountain areaare analyzed according to the date from the weather and the hydrometric stations in the area, theresults show that effects of El Nino events to temperature, precipitation and runoff are different in thedifferent time and zones. When El Nino occurs, temperature rises, but precipitation and runoff decreasein the whole Qilian mountain area, especially in the east and middle parts of the area. Temperaturerises, precipitation and runoff still decrease in the eastern Qilian mountain area in the next year ElNino occurring, but decrease extent is fewer. There are not obvious relationship between temperature,precipitation and runoff with El Nino events in the western Qilian mountain area.
