Abstract：There is a great significance of revealing the characteristics of regional environment evolution and global change to the research on arid Lop Nur areas. By the “Ear” features of Lop Nur in remote sensing image, the spectrum, soil and surface parameters were analyzed. The differences in total salt content in soil and the surface structure bring are cause directly for the “Ear” features in remote sensing image; The results of the analysis of spectrum, total salt content and particle size are in good agreement. “Ear” features recorded the process of environmental change. The process implys that Lop Nur dried up gradually under the impact of global change. The adjustment during the process of drying up let Lop Nur experience two relatively humid climates, with the previous a little longer, the later very short.
