[Objective] The effects of runoff scouring under different slope gradients and land use types on slope runoff， sediment yield， and nitrogen （N） and phosphorus （P） losses were analyzed， in order to provide theoretical support for soil and water conservation in Dabie Mountain region of western Anhui Province， China.[Methods] Field in situ scouring experiments were conducted on 15o and 20o slopes undergoing typical land-use types （bare land， grassland， tea garden， forest land and bamboo forest） in the Jiangzihe small watershed， Huoshan County， Anhui Province. Considering the frequent heavy rainfall in the region， a scouring flow rate of 9 L/min was applied to analyze the responses of runoff， sediment yield and nutrient losses to land-use types and slope gradients. [Results] ① During the scouring process， the stabilized average runoff rate on the 15o slopes was in the following order： bare land > tea garden > grassland > forest land > bamboo forest， whereas the sediment yield rate on the 20o slopes were ranked as follows： bare land > grassland > tea garden > forest land > bamboo forest. Compared to the 15o slopes， the runoff rate on the 20o slopes increased significantly only for bare land， with negligible changes in other land-use types. At a stabilized sediment yield， the sediment yield rate of the 20o slopes was slightly higher than that of the 15o slopes， with both exhibiting the following order： bare land > tea garden > grassland > bamboo forest > forest land. ② Total N （TN） and total P （TP） losses on the 20o slopes were marginally higher than those on the 15o slopes. Under the same slope gradient， TN and TP losses showed the following pattern： tea garden > bare land > bamboo forest > grassland > forest land. ③ Throughout the scouring process， runoff predominantly contributed to TN loss， whereas sediment played a more significant role in TP loss. [Conclusion] Expanding area of bamboo forest cover in the Dabie Mountains of western Anhui Province can effectively enhance water conservation and soil retention. Additionally， tea gardens should be prioritized for non-point source pollution management to mitigate the losses of nutrients， such as N and P.
