A review of desertification research on the Tibetan Plateau
As the most serious ecological and environmental problem in Tibet Plateau in recent years,desertifi-cation not only determines the ecological and environmental quality of the entire Qinghai-Tibet Plateau,but also affects the sustainable development of the ecological environment in China.This paper reviews the latest progress of desertification research on the Tibetan Plateau from four aspects:spatial and temporal distribution pattern of desertification,formation process of aeolian sand landform,vegetation sand control measures and desertification monitoring techniques.According to the existing problems in the study of desertification on the Tibetan Plateau,the future research priorities were put forwarded:(1)increase the overall study of desertification regionality and the linkage between upper,middle and lower rivers in the Tibetan Plateau.(2)identify the sources of sand mate-rials and their relative contributions to the aeolian processes in river valleys.(3)analyze the effects of vegetation sand control measures on the movement of sandy materials.(4)establish a new technology for monitoring desert-ification on the Tibetan Plateau.Some suggestions on desertification control in Tibet Plateau were put forwarded in order to provide reference for the sustainable development of ecological environment in Tibet Plateau.
