Salinization is one of serious disasters in Minqin Oasis, northwestern China, and it has close relationship with natural changes and human activities. Using TM time-series images temperature and NDVI are evaluated and salt lands have special distribution in the two dimensions space. With the three principal components of the original images these two useful layers were used to get the distributions of salt lands in the four years. The changes of salt lands are diagramed that tell us that the trend of salinization in Minqin Oasis is in reduction from 1987 to 2000 year and it is the result of reduction of groundwater. With regard to analyzing the reason of salt land changes nature and manmade influences are discussed.
