Test environment for simulating topography and landform of complex Mars landform

The invention discloses a test environment for simulating the topography and landform of complex Mars, which comprises seven terrains, namely a coarse sand area, a loose rock area, a sharp-corner rock area, a rounded-corner rock area, a slate area, a medium sand area and a fine sand area, and is characterized in that the coarse sand area is used for simulating the surface flat plain environment of the Mars; the medium sand area is used for simulating a canyon plain environment on the surface of the Mars; the fine sand area is used for simulating a Mars surface sand dune environment; the loose rock area is used for simulating a sand environment with sharp-corner and rounded-corner rocks on the surface of the Mars; the sharp-corner rock area is used for simulating a sand environment with irregular rocks on the surface of Mars; the rounded-corner rock area is used for simulating a sand environment of regular rocks on the surface of Mars; the slate area is used for simulating a mars surface batholith environment. According to the test environment, simulation of the Mars soil environment and the topography and landform is realized, and all test conditions required in the test process and comprehensive requirements on the Mars soil and the surface topography and landform of the Mars are met.
