Abstract:In 2002,using RS and GIS,we completed quantitative dynamic contrastive monitor of entironment up-to-date state of whole Alxa league in 1996,2000 and 2002.Choosing the United States Landsat 7 ETM data in 2000 and 2003 and Landsat 5 satellite TM data in 1996 as current and past aspection and using the Remote Sensing technique including image resolution merge、dynamic monitor、supervised classification etc,we quantificationally acquired the entironment up-to-date state of Alxa league within 7 years.By validating 132 outside samples,acquired dynamic monitor data and established understratum database of the entironment of Alxa league.Supportted by the “sea quantity” GIS database,we carried out quantitative dynamic analyzing of entironment of the whole Alxa league.This paper introduces the quantitative dynamic analyzing result of the entironment of Alxa league.
Keywords:“3S”technicque  entironment  hungriness sight  ejina oasis  haloxylon ammodendron
