Characteristics of artificial vegetation community in sandy areas on the east shore of Qinghai Lake

Plant community characteristics in several artificial revegetation areas in sandy areas on the east shore of Qinghai Lake were studied based on restoration ecology, species diversity and functional diversity of different artificial communities in revegetation using ecosystem localization research method． Three types of artificial plant communities were identified: the ‘Artemisia-Hippophae’ community, the ‘Artemisia-Salix’ community and the ‘Hippophae-Artemisia’ community． The artificial community cover was found to have the same trend of change as shrub layer cover． Artificial community, where a higher recovery level could be achieved with mixed planting of multiple layers, showed better species diversity and functional trait diversity than other communities． These findings provide theoretical support for re-vegetation and ecosystem restoration in alpine desert areas, particularly in the selection of seedlings and optimal allocation of resources for artificial restoration communities in the construction of wind and sand control projects in alpine deserts．
