The conventional identification of salinizated soil is based on the laboratory results of soil specimen. It can not be applied continuously to the investigating area inch by inch due to high cost and heavy work of dense sampling rate. However, the correlation among Ground Penetration Radar(GPR) information and soil salinity, pH value, organism and water content enable us to formulate a method with which parameters above specified may be investigated. Theoretical study show that the existence of variations in soil chemical and physical properties results in correlated response in geometry and dynamics in GPR waveforms and their amplitude. The field experiment indicates that GPR method would be a feasible technique with fast speed for evaluation of environmental properties of soil salinization.
