中文摘要	以塔克拉玛干沙漠高大沙垄区垄间地防沙治沙工程下风向沿主风向连续分布的4个新月形沙丘为研究对象,研究了沙丘表面不同部位表层沙粒粒度特征,明确防沙治沙工程对沙丘表面沙粒粒度的影响,揭示沙丘表面沙粒粒度空间分布规律.主要结论:防沙治沙工程对于风沙环境的影响是显著的,表现为在防沙治沙工程影响区范围内沙丘表层沙粒明显细化.本文的相关研究结果将为阐明类似人为扰动条件下沙丘表面气流场和沙粒运移规律提供基础数据.
英文摘要	Characteristics of grain-size over sand dunes is an important factor for its surface flow and morphology.Although this is a well-studied area,few reports worked on characteristics of grain size over sand dunes under wind direction of anthropic disturbance,such as engineering system of prevention and control of desertification that is typical anthropic disturbance on migratory dunes in Taklimakan desert.Any such work would be important to confirm effects of such anthropic disturbance on aeolian sand activities.Characteristics of grain-size are important factors reflecting aeolian sand activities.Based on sand grains over four barchan dunes distributed downward engineering system of prevention and control of desertification of Taklimakan desert highway along wind direction in interdune corridor of ridges,this paper studied characteristics of grain-size at different positions over sand dunes and the influence of engineering system of prevention and control of desertification and revealed spatial distribution of sand grains over dunes.These data provide a basis for clarifying surface flow and grain transport over sand dunes of such kind of anthropic disturbance.
