Abstract
The article analyzes the statistical date of annual precipitation,runoff,sediment runoff for lengkou Hydrologic Station of Taoshi River from 1976 to 2009 year.Analyzed results indicate that the precipitation,runoff and sediment runoff mainly concentrate in flood season,the correlation between annual precipitation and annual runoff is obvious,but the correlations between annual precipitation and annual sediment runoff or between annual runoff and annual sediment runoff are not obvious.
