The invention discloses a device for simulating soil micro-plastic migration in a karst region, which comprises a simulation box, a leakage piece with adjustable aperture is arranged in the simulation box, a simulation soil layer is laid at the top end of the leakage piece, and a water flow collection assembly is communicated between the bottom end of the leakage piece and the inner wall of the bottom end of the simulation box, in the simulation soil layer and on the surface of the simulation soil layer. The water flow collecting assembly is communicated with one side of the lower end of the simulation box; the supporting piece is arranged outside the simulation box, and the inclination angle of the simulation box is changed through the supporting piece; the rainfall piece is arranged above the simulation box and corresponds to the opening in the top end of the simulation box. The device can simulate the migration condition of soil micro-plastics in the karst region, has multiple functions, and can simulate t
