In the late part of the active developing period, the temporal variation of sediment concentration and sediment transport ratio of each rainfall can be expressed by exponent function and the variation presents quadratic polynomial function in the stable developing period. the spatial variation character of sediment yields with space of the experimental watershed model. the active position of soil erosion and sediment yield of the experimental watershed model changes from the downside to the upside with the developing process of the watershed model
流域模型侵蝕產沙空間變化特徵侵蝕產沙的活躍部位隨流域模型發育過程呈現由流域模型下部逐漸向上部發展特徵，其中流域模型下中部為發育初期時段和發育活躍時段侵蝕產沙的活躍部位，流域模型上部是發育穩定時段侵蝕產沙的活躍部位。 -
It is concluded that the phenomena of replacement of spatial and temporal process is typical in the erosion development, the coarsen of riverbeds, the sediment concentration and the change of river regime, etc
