Abstract:: The effect of water and sediment research is an important theoretical foundation for the practice of the soil and water conservation planning and management.Based on the Tuwei river catchment’s precipitation,runoff,sediment data,using Mann-Kendall rank correlation method and a total anomaly method to analyze the characteristics of water and sediment and its trends.Contrary to precipitation and human activities factors which affect water and sediment changes,using comparative analysis of time series and precipitation-sediment dual-accumulation curve to calculate sediment attenuation caused by precipitation change and soil erosion control during different times and their proportions.And so determine soil and water conservation measures on the impact of sediment discharge.Analysis showed that soil and water conservation measures on the impact of changes in river basin sediment very different in different time slots.Soil and water conservation measures is the main driving force of sediment attenuation in 20th century 70s.And the most obvious change occurred in July and August.
