In order to quantitatively evaluate the sediment reduction benefits of the Yudi dams in the Ten Tributaries area, and according to the historical datasets collection and detailed field investigation, we counted the number and distribution characteristics of existing check dams in the Ten Tributaries since 1986, the generalization method was conducted to determine the main parameters affecting the sediment retention, a total of 354 check dams in the study area were surveyed. The results showed that the 354 check dams in the Ten Tributaries had trapped a total of 32.056 1 million tons of sediments; the largest amount of sediment reduction in the Xiliugou was observed, which reached up to 12.397 6 million tons; the results of the sediment reduction characteristics of the check dams in different periods showed that the amounts of sediment reduction were 4.946 6×106 tons, 1.155 57×107 tons, and 1.555 38×107 tons in 1986—1999, 2000—2009, and 2010—2018, respectively. The check dams in the Ten Tributaries area had significant sediment reduction effects,which had high sediment reduction index(5 720.33~58 141.81 tons per check dam). After 2000, the sediment reduction of the check dams still increased with the increase of forest and grass measures on the slope, suggesting that the check dams is the one of the most effective soil and water conservation measures in the Ten Tributaries area.
