摘　　要：西藏高原沙漠化作为近年来最严重的高原生态环境问题,不仅决定整个西藏高原的生态环境质量,还影响着中国生态环境的可持续发展。本文从西藏高原沙漠化时空分布格局、风沙地貌形成过程、植被防沙措施及沙漠化监测技术4个方面,综述了西藏高原沙漠化研究最新进展。根据当前西藏高原沙漠化研究中存在的问题提出今后研究重点:(1)增加西藏高原沙漠化区域性和河流上中下联动整体研究;(2)明确沙物质来源及其对河谷风沙的相对贡献;(3)分析植被防沙措施对沙物质移动的影响;(4)构建适用于西藏高原沙漠化监测的新技术。对西藏高原沙漠化防治提出建议,以期为西藏高原生态环境可持续发展提供参考。As the most serious ecological and environmental problem in Tibet Plateau in recent years,desertification 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 materials 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 desertification 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.
