The invention relates to a method and a device for measuring indoor resistivity of a soil sample. The method is characterized by comprising the steps of 1) preparing a sample placing device (2) and a direct-current resistivity measuring instrument (5) according to measurement requirements, fixing the soil sample (1) on the sample placing device (2), and connecting the sample placing device (2) with the direct-current resistivity measuring instrument (5) by a four-electrode method; 2) starting the device and setting parameters according to operation procedures of the direct-current resistivity measuring instrument; 3) beginning to acquire and record voltage, current and resistivity values Rho 1 after parameter setting is finished; 4) re-measuring the voltage, the current and the resistivity values Rho 1 after previous measurement is finished and two receiving electrodes are swapped, and recording measured voltage, current and resistivity values Rho 2; 5) further reducing a polarization effect by using a superp
