【Abstract】 omparision analyses were carride out for water and soil conservancy areas developed usingvarious measures, sediment reduction indexes of various measures, and amount of sediment reduced byvarious measures. The study included 14 tributaries of the Yellow River in the region of Hekouzhen toLongmen. Results obtained (using water and soil conservancy method) from the Fund of Water andSoil Conservancy, the Fund of Water Runoff and Sediment Yield, and the Fund of Natural Sciencewere used.
