数据为塔里木河流域10万沙漠分布图，本数据以2000年TM影像为数据源，进行解译、提取、修编，利用遥感与地理信息系统技术结合1:10万比例尺成图要求，对沙漠、沙地和砾质戈壁进行专题制图。数据属性表：area（面积）、perimeter（周长）、ashm_(序列码）、class（沙漠编码）、ashm_id（沙漠编码）其中沙漠编码如下：流动沙地 2341010、半流动沙地 2341020、半固定沙地 2341030、戈壁 2342000、盐碱地 2343000.

The special mapping of deserts, sandy land and Gravel Gobi is carried out by using remote sensing and GIS technology in combination with the mapping requirements of 1:100000 scale. Data attribute table: area, perimeter, sequence code, class and ID. the desert codes are as follows: mobile sand 2341010, semi mobile sand 2341020, semi fixed sand 2341030, Gobi 234200, saline alkali land 2343000
