中国1：10万戈壁数据集（2000年）

为了更准确了解我国戈壁时空变化规律，从国家层面收集、整编和更新戈壁数据集资料，在遥感和地理信息系统技术支持下，参考已有荒漠调查监测成果，以Landsat系列影像数据为主要信息源，按同一解译标准、人机交互方式按1：10万比例尺成图要求，比较提取戈壁信息，形成中国2000年戈壁分布现状数据，并通过地面调查进行精度验证和评价后建立数据库。To accurately understand the spatio-temporal variation patterns of the Gobi in China, we collected, compiled and updated Gobi-related dataset materials at the national level. Supported by remote sensing and geographic information system (GIS) technologies, and drawing on existing desert survey and monitoring results, we selected Landsat series image data as the primary information source. Following unified interpretation standards and human-computer interaction workflows while complying with the 1:100,000-scale mapping specifications, we conducted comparative extraction of Gobi information. The dataset representing the current distribution of the Gobi in China in 2000 was thus generated, and a dedicated database was established after accuracy validation and assessment through field investigations.
