The invention relates to a basin-scale water-erosion fine simulation simulation test method which is used to systematically research soil erosion process and mechanism of a small-basin different-landform unit. According to the method, especially, different landforms can be constructed according to test requirements, soil with different particle sizes is used to fill the landforms, the soil bulk density of different-landform positions of the basin is artificially controlled, water-soil conservation measures are laid on different-landform positions (the upper part of a slope surface, the lower part of a slope surface, ditches and the like) of the basin, different rainfall intensity and rainfall processes are controlled, the hydrodynamics characteristics of a water flow at different-landform positions are observed, so that precise simulation of a water and soil loss process of the basin under different site conditions and different rainfall conditions is realized, and influence and response mechanism of various factors on the soil water-erosion process under different underlying surface conditions are researched.
