Abstract: Soil salinization is one of main characteristics of land degradation.Under the influence of natural and human factors,the spatial and temporal distribution of soil salinization is dynamic changeable.In order to know the distribution data bases and find out the relationships between variation of distribution and influencing factors,we conducted location monitoring and restoring of soil salinization maps drawn by remote sensing technique in different periods,and set up grey theory predictable model and determined the mathematical relation between artificial control method and soil salinization development, thus provided basis for improving and utilizing salinized soil.
