2022年塔克拉玛干沙地表样品粒度数据集，由本项目野外考察生产所得，包括样点经度，维度，样点说明，粒径分级及体积百分含量五个字段，共计480条记录。所有数据均来自野外采集，采集过程中，严格按照库木塔格沙漠风沙地貌一书所描述的沙物质样品的采集方法，即：在采样点选取约20cm * 20cm面积的沙面，均匀采集表面0-1 cm的沙粒，样品重量500-1000g。在后期的样品加工过程中，选取了具有粒度测量资质的陕西师范大学激光粒度实验室进行室内分析，粒度分析采用了马尔文3000粒度仪，测量结果为体积百分含量。

All data are collected in the field. During the collection process, the collection method for sand samples described in the book \"Wind-sand Landforms of the Kumtagg Desert was strictly followed, that is, a sand surface with an area of about 20cm * 20cm was selected at the sampling point, and the sand particles with a surface of 0-1 cm were evenly collected, and the sample weight was 500-1000g. During the later sample processing process, the Laser Particle Size Laboratory of Shaanxi Normal University with particle size measurement qualifications was selected for indoor analysis. The particle size analysis used a Malvern 3000 particle size analyzer, and the measurement results were volume percentages.
