中国1：10万戈壁数据集（2015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2015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 spatiotemporal variation patterns of Gobi in China, this study collected, compiled, and updated national-level Gobi dataset resources. Supported by remote sensing and geographic information system (GIS) technologies, and referencing existing desert survey and monitoring results, Landsat series image data was adopted as the primary information source. Following unified interpretation standards and human-computer interaction methods, and complying with the mapping requirements at a scale of 1:100,000, Gobi information was extracted through comparative interpretation, thus generating the current distribution dataset of China's Gobi in 2015. Finally, the database was established after accuracy verification and evaluation were carried out via field surveys.
