[Objective] To study the relation between soil erosion and landuse patterns, in order to provide useful information for coastal water environment protection and the integrated river basin management in Jiaodong peninsula.[Methods] Taking Jiaodong Peninsula as the case study area, we evaluated soil erosion and sediment flux into coastal waters by using N-SPECT model and RS and GIS techniques.[Results] The high loads of soil erosion were found in eastern and southern coastal areas in Jiaodong peninsula, while low loads were mainly distributed in the middle and central region of the study area. The three watersheds (Dagu, Wulong and Dagujia river) contributed most to the soil erosion and sediment transportation. The sediment flux to coastal waters through shorelines exhibited high complicated spatial patterns, coastal areas in Yangcheng District, Southern Qingdao(Jiaonan City), Eastern Laizhou bay and the southwest of Weihai City have the highest sediment flux.[Conclusion] Both soil erosion and sediment were closely related to watershed land use, generally, farmland dominated areas have the most severe soil erosion, while woodland and grassland could prevent soil erosion to a great extent.
