Abstract: Effects of ecological restoration in alpine sandy lands was studied at Huangshatou,Qinghai Province,where land desertification was heavy and whose sandy lands were representative on Qinghai-Tibet Plateau.The results showed that enclosure,inter-dune planting,and sand barriers were able to facilitate the process of revegetation or vegetation restoration,characterized by the enhancement of vegetation cover,cover of indicator or dominant species indicating late stage of succession,and species richness of perennial grass;Because the process of plant establishment was prevent by drifting sand from uncontrolled sandy land at the edge of controlled sandy land,vegetation restoration were slower there than in the core part.For the sake of better rehabilitation,an improvement was recommended therefore on how to control sandy lands.Even if the negative "edge effects" occurring in the process of vegetation restoration could hardly be removed thoroughly,they may be weakened and confined to some extent through enlarging the area of controlled sandy land.If so,the area proportion of core part to edge would be enhanced,and then more lands would be given the chances to restore their vegetation.
