The invention provides a stereoscopic porous polyimide film preparation method based on gaseous poor solvent induction forming. The method is characterized by comprising steps as follows: solid polyimides are dissolved in a good solvent, a polyimide solution is obtained, a poor solvent is added to the polyimide solution and is stirred and mixed, and a coating solution is obtained; the coating solution is defoamed and then is used for film coating, the prepared polyimide film is subjected to pore forming through gaseous poor solvent induction and then is subjected to washing, drying and stretching setting, and the stereoscopic porous polyimide film is obtained. According to the prepared stereoscopic porous polyimide film, surface and internal pore forming is uniform, the pore diameter, the breathability and the porosity are adjustable, the heat resistance is good, and the film can be used for a long time at the temperature of 300 DEG C or higher.
