Artificial drainage basin suitable for researching rainfall-stratified runoff relationship

The utility model relates to an artificial drainage basin, in particular to an artificial drainage basin suitable for researching rainfall-stratified runoff relationship, which comprises three parts,namely a main body part, an input part and an output part of the artificial drainage basin. Wherein the main body part comprises a drainage basin boundary (1), an experimental soil body (2), longitudinal flow collecting ditches (3) and transverse flow collecting ditches (4); the input part comprises an artificial rainfall system and a measuring station network. The output part refers to an observation room (7) of the artificial watershed, layered flow measuring weirs (9) are arranged according to the number of the flow collecting grooves, and water sample collecting points of the system are arranged. Compared with the traditional research on the rainfall-stratified runoff relationship of a natural experiment drainage basin, the device disclosed by the utility model can be used for accurately measuring hydrological
