塔里木河流域1:10万沙漠沙地分布图(2000年)

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.

This dataset is a 1:100,000-scale desert distribution map covering the Tarim River Basin. It was developed using 2000 vintage TM (Thematic Mapper) imagery as the primary data source, via workflows including image interpretation, feature extraction and map revision. By integrating remote sensing and geographic information system (GIS) technologies and complying with the 1:100,000-scale cartographic specifications, thematic mapping was conducted for deserts, sandy lands and gravel Gobi. The data attribute table includes the following fields: area, perimeter, ashm_ (sequence code), class (desert code), and ashm_id (desert code). The corresponding desert codes are as follows: Shifting sandy land: 2341010; Semi-mobile sandy land: 2341020; Semi-fixed sandy land: 2341030; Gravel Gobi: 2342000; Saline-alkali land: 2343000.
