Abstract: According to quadrat survey data belonging to 4 sample plots of 36 sample areas in the Minqin during the Period of 2006-2014,we analyzed the community structure and species diversity of Artemisia desertorum, Chenopodiaceae, Ephedra przewalskii Stapf and Nitraria tangutorum Bobr. The results showed: The structure of community was simple. The species was homogeneous and small number, the plants were low bud nodes to adapt to the habitat conditions. Little changed of Shrub layer species,and herb layer species had increased.The diversity index of Artemisia desertorum community, Chenopodiaceae community and Nitraria tangutorum Bobr community increased slightly, and the community of Ephedra przewalskii Stapf decreased slightly. The changes of community structure and species diversity in this area were mainly due to the changes of species in the herb layer. Understanding and mastering changes of structure and species diversity of desert plant communities in Minqin,for the promotion of arid desert vegetation restoration and conservation of species diversity to provide evidence.
