| Abstract: | Based on the principle of scientificalness and computer operability,with the help of analytical method of combining multi-disciplinary with 3S technology,the classification system and interpretation signals of soil salinization were established.The study shows that the area of soil salinization is the product of combination of natural and human factors,and human activities contribute to the development of salinization;in addition,soil salinization is mainly distributed in the north and west parts of the Tar... |
