Abstract: On this paper the composition of plant species, structure and dynamics of the artificial vegetation under non-irrigation condition along the north side of the Shapotou section of the Baolan railway are discussed. It is predicted that if the artificial vegetation experimental plots are to be excluded continuously as it is, then, in the fixed section of the plots, planted Hedysarum scoparium, Coragana korshinskii and Artemisia ordosica, despite later can regenerat naturally at present time, will allrecede from the plots in twenty years.In the last of this paper, author put forward some suggestions for future researches under this subject.
