Simulation of Soil Salinization Based on T-PROGS

According to the basic principle of the geological transition probability statistics software(T-PROGS),soil salinization three-dimensional structure model in research area was established using the known soil salt content in profile,and soil salinization was simulated by TSIM.The results indicated that:the mild salinization type and the moderate salinization type were the main salinization types in the study area,and their isotropic distribution ratios accounted for 34.0%and 54.1%,which represented that the distributions in vertical and horizontal directions were strong consistent.Distributions of no salinization,severe salinization and solonchak were relatively discrete.There were higher precision for mild salinization and moderate salinization types according to TSIM simulation.
