Satellite remote sensing technology has a lower detection depth on salinization soil monitoring, it can not meet the actual de-mand of salinization soil management. This study explored the salinization soil detection method using 100 MHz low-frequency ground penetrating radar ( GPR) , determined that 100 MHz GPR electromagnetic wave propagation velocity has a significant correlation rela-tionship with soil salt content or soil conductivity of each soil layer. The result of regression analysis between GPR electromagnetic wave propagation velocity and salt content or conductivity of each soil layer proved that electromagnetic wave propagation velocity of GPR can be used to estimate soil salt content or soil conductivity quantitatively with a good accuracy, furthermore, low-frequency microwave GPR has a deeper detecting depth. This study provided a reference for salinization soil detection using low-frequency GPR quantitative-ly, and supplied a new technical method for salinization soil detection.
