The invention discloses a wind erosion test device for combined sand fixation, which comprises a base for placing a sample, a pressure chamber arranged on the base, a sealing cover arranged on the outer side of the pressure chamber, the pressure chamber connected with a pressure chamber exhaust valve and an air inlet pipe, high confining pressure is provided for the sample by injecting gas, and a pressure gauge is arranged on the air inlet pipe; a sample cap and a control bolt are arranged at the top of the sample; a temperature-controlled heating device is mounted at the lower end of the base. According to the invention, different temperature and high pressure conditions can be simulated to ensure that a sample can be cured and formed by using a biomineralization technology under different constant temperature and high pressure conditions, so that the filling effect of filling an ore goaf by using a biotechnology after an underground ore body is mined in a project can be researched through the curing effect;
