利用11004幅中巴资源卫星CCD和陆地卫星TM/ETM遥感影像，按照预先制定的解译规则，对中国湖泊的空间变化特征进行了分析。该数据集由6843幅数字光栅图像（1：100000和1：50000），全国数字矢量数据集（1：250000）和历史文献支持。用降水量数据对比较数据进行了季节变化校正。目前，中国有2693个天然湖泊，面积大于1.0 km（2），不包括水库。这些湖泊分布在28个省、自治区、直辖市，总面积81414.6平方公里，约占中国陆地总面积的0.9%。在过去的30年中，新形成和新发现的面积大于1.0 km（2）的湖泊数量分别为60和131个。相反，243个湖泊在此期间消失。
Based on 11004 satellite images from CBERS CCD and Landsat TM/ETM, changes in the spatial characteristics of all lakes in China were determined following pre-established interpretation rules. This dataset was supported by 6843 digital raster images (1:100000 and 1:50000), a countrywide digital vector dataset (1:250000), and historical literature. Comparative data were corrected for seasonal variations using precipitation data. There are presently 2693 natural lakes in China with an area greater than 1.0 km(2), excluding reservoirs. These lakes are distributed in 28 provinces, autonomous regions and municipalities and have a total area of 81414.6 km(2), accounting for similar to 0.9% of China's total land area. In the past 30 years, the number of newly formed and newly discovered lakes with an area greater than 1.0 km(2) is 60 and 131, respectively. Conversely, 243 lakes have disappeared in this time period.
