This paper examines the impacts of precipitation on sediment discharge and runoff of typical reach and catchments of the Yellow River during 1960-2011.This study implies mathematical statistics and geospatial interpolation for temporal and spatial analysis of sediment transport modulus,annual runoff and precipitation.Results indicate that: 1)sediment transport modulus and annul runoff decreased during 1960-2011 at 99% confidence level through Mann-Kendal test and the temporal change of them is more significant since 1980sr,and the decreasing tendencies of sediment transport modulus and annual runoff are more obvious in downstream and both of them decreased from upstream to downstream during the same period;2) for annual precipitation,sixteen meteorological stations display decreasing trend and other five stations display fluctuating trend,and temporal variability is obvious for the temporal variation coefficients of annual precipitation are greater than 20%;3)generally speaking,the proportion of summer precipitation is the largest among the four seasons and precipitation in summer play an important role in influencing sediment discharge and annual runoff;4) temporal distribution of erosive precipitation are nearly consistent with annual precipitation,and erosive precipitation plays the leading role in resulting sediment discharge and soil erosion;5) precipitation and sediment transport modulus are positive correlated---the increase or decrease of precipitation will cause increase or decrease of sediment transport modulus and annual runoff,and soil erosion and sediment discharge are mainly caused by erosive precipitation and rainstorm.Precipitation variability is the leading factor influencing sediment discharge and annual runoff without effects of human activities and other factors.
