摘要 Runoff formation is a complex meteorological-hydrological process impacted by many factors, especially in the inland river basin. Based on the data of daily mean air temperature, precipitation and runoff during the period of 1958-2007 in the Kaidu River watershed, this paper analyzed the changes in air temperature, precipitation and runoff and revealed the direct and indirect impacts of daily air temperature and precipitation on daily runoff by path analysis. The results showed that mean temperature time series of the annual, summer and autumn had a significant fluctuant increase during the last 50 years (P?
