Abstract：As an important parts of watershed hydrology research,study on runoff and sediment process is the fundamental content of watershed hydrology modeling.The watershed in West of Shanxi Province which is a national forestry ecology research station was analyzed by experiments,runoff and sediment process from different types of land use was researched by contrastive analyzing.The results show that during the representative rainfall events(rainfall amounts: 8.6 mm and 13.6 mm),suspended sediment concentration varies synchronizing with flow discharge in agricultural and stock breeding watershed.And it is obviously that peak of suspended sediment concentration lags behind flood peak in natural forested watershed.Modules of surface flow and sediment yield were highest as 2.40%、6.40% and 6.71 t/km2、73.69 t/km2 in agricultural watershed,and lowest as 0.13%、0.75% and 0.02 t/km2、6.95 t/km2 in natural forested watershed.
