Abstract：Plantation of different species was made in Hangyangtan Sandland.Effects of natural vegetation restoration and difference of wind erosion in stands were studied in 7 years after plantation to provide scientific basis for Hangyangtan Sandland and other similar areas.Natural vegetation restoration process was speed up in Caragana microphylla and Platycladus orientalis stands based on species richness,the opposite effect in the Populus alba var.Pyramidalis and Populus euramercana 107 stands,and little effect in Elaeagnus angustifolia and Ulmus pumila stands.The undergrowth was dominated by annual herbs in the P.alba var.pyramidalis and P.euramericana 107.A slight increase of the shrubs and perennial herbs were found in the E.angustifolia and U.pumilaforests.And the life-form spectra tended to diversification in the C.microphylla and P.orientalis stands.Observation data showed that wind erosion was most serious in the P.alba var.pyramidalis and P.euramericana 107 stands,and that in the E.angustifolia and U.pumila forest was the second.Natural vegetation similarity coefficient in the same desertification stage is higher than the value in different stages of those stands.So C.microphylla and P.orientalis are the best choice as afforestation species,E.angustifolia and U.pumilaforests are the second,and P.alba var.pyramidalis and P.euramericana 107 should not be chosen.
