Reported here are the results with respect to some key problems in stabilizing the shifting dunes by vegetation in the central Taklimakan: plant selection

combination

density planting season and rational irrigation. Salt accumulation and it effects on plant growth in response to different irrigation management are also compared.It is revealed that salt water with degree of mineralization over 7.416 g/L limits the growth of some less salt-resistant plants. Ditch irrigation using salt water with degree of mineralization less than 4.13 g/L has no negative effects on shrub growth in short period. While under drip irrigtion

the salt accumulation limits shrub growth to some extent. Bleaching can reduce salt accumulation.
