Taking　the　Zhuxi　watershed　in　Changting　County　of　China　as　the　study　area,　soil　erosion　is　estimated　by　using　SWAT　model.　The　runoff　sediment　data　from　2013-2015　years　of　Hetian　hydrologic　station　are　used　for　the　model＇s　calibrations　and　correction.　The　experimental　results　showed　that　the　simulated　results　from　the　SWAT　model　with　the　correction　parameters　could　reflect　the　actual　situation　of　the　study　area　objectively.　The　estimation　results　show　that　the　main　soil　erosion　types　in　the　watershed　are　mainly　micro　and　light　erosion,　the　area　of　moderate　and　serious　erosion　is　small　and　these　areas　are　mainly　distributed　in　the　central　region.　Among　all　kinds　of　land　use　types,　the　soil　erosion　modulus　of　bare　land　is　maximal,　while　the　absolute　value　of　sediment　yield　in　forest　land　is　largest　for　its　largest　area.　©　2017　IEEE.
