Abstract: In Bashang, an area with very fragile eco-environmentin north China, three typical sub-areas, south of Duolun, west of Weichang and north of Fengning, were selected.Using Landsat TM satellite images of 1987, 1999 and 2004, supervised classification and transfer matrix were applied to studythe dynamic changes of land use and soil desertification in this area.The results show that eco-environment has dual nature—deterioration and reversion, and active ecological construction can effectively deter the deterioration of eco-environment.From 1987 to 1999, eco-environment continued to deteriorate and soil desertification was extended.Since the Project of Jing-Jin Sand-Storm SourceControl, which was centered on ecological construction, carried out in 1999, the trend of eco-environment deterioration has been inhibited significantly.
