Land-use　change　is　one　key　factor　influencing　the　hydrological　process.　In　this　study,　the　Hun　River　Basin　(HRB)　(7919　km(2)),　a　typical　alpine　region　with　only　four　gauge　meteorological　stations,　was　selected　as　the　study　area.　The　China　Meteorological　Assimilation　Driving　Datasets　for　the　SWAT　model　(CMADS),　widely　adopted　in　East　Asia,　was　used　with　the　Soil　and　Water　Assessment　Tool　(SWAT)　model　to　simulate　runoff　and　sediment　yield　responses　to　land-use　change　and　to　examine　the　accuracy　of　CMADS　in　the　HRB.　The　criteria　values　for　daily/monthly　runoff　and　monthly　sediment　yield　simulations　were　satisfactory;　however,　the　validation　of　daily　sediment　yield　was　poor.　Forestland　decreased　sediment　yield　throughout　the　year,　increased　water　percolation,　and　reduced　runoff　during　the　wet　season,　while　it　decreased　water　percolation　and　increased　runoff　during　the　dry　season.　The　responses　of　grassland　and　forestland　to　runoff　and　sediment　yield　were　similar,　but　the　former　was　weaker　than　the　latter　in　terms　of　soil　and　water　conservation.　Cropland　(urban　land)　generally　increased　(increased)　runoff　and　increased　(decreased)　sediment　yield;　however,　a　higher　sediment　yield　could　occur　in　urban　land　than　that　in　cropland　when　precipitation　was　light.
