Based on community succession and analysis of sand flow,the stability of com munity was studied.In Shapoptou area,the artificial communities in which Artemisia ordosica communi ty is dominant are adaptable to the habitat environment in long-term natural succession and they are stable.The results of observation and comparative study of vegetation succession in Shapotou and the vicinity showed that existing vegetation communities are evolving towards disclimax and in the future long periods of time Artemisia ordosica community will be stable.These succes-sions can facilitate the evolution of the local artificial vegetation towards more stable artificial natural compound ecosystem and even natural ecosystem.Furthermore,the research result of im-pact of wind flow on plant and earth-surface wind-tunnel experiment result showed that main vegetation and earth-surface of Shapotou at present can resist greater stress from wind flow and the ecosystem that can stand sand-dust storms has been formed.
