Abstract:: With fixation of mobile sand dunes,the natural vegetation that are adaptable to move sands will be replaced by those adaptable to fix sand dunes due to changes of such ecological factors as soil and water.The natural vegetation in Gaotai desert area has changed greatly within 25 years.The original plant community of Tamarix ramosissima+Artemisia arenaria+Headysarum scoparium has changed into the community of Tamarix ramosissima+Artemisia ordosica+Headysarum scoparium,with vegetation coverage of 42%;the community of Calligonum mongolicum+Tamrix ramosissima+Artemisia ordosica has changed into Tamarix ramosissima+Apocynum venetum+Artemisia ordosica,with the vegetation coverage of 39%;the community of Head ysarum scoparium+Artemisia arenaria+Tamarix ramosissima+Alhagi sparsifolia has been replaced by Tamarix ramosissima+Apocynum venetum+Headysarum scoparium+Artemisia ordosica+Alhagi sparsifolia,with the vegetation coverage of 65%;the community of Calligonum mongolicum+Reamuria soongorica has been replaced by Tamarix ramosissima+Alhagi sparsifolia.
