However,the ectone between the oasis and desert is the most drastic and prominent area in the activities as above。It records the most sensitive and intact information on the transition belt. It is significant to further the study on the environmental evolvement and formation mechanism, and this helps to open out its ecological essential,protect and develop the oasis。The remote sensing is a rising and booming subject and the development of the technology of the remote sensing offers the new source of the data and the new way to explore astrospace.. Now ,there are many countries who send their own satellites to observe the earth land. So they give us so many data .The paper use landsat’s image to get the information of underground water and the distribution of man made water system .
