英文摘要Data and knowledge of surface water bodies (SWB), including large lakes and reservoirs (surface water areas > 1 km(2)), are critical for the management and sustainability of water resources. However, the existing global or national dam datasets have large georeferenced coordinate offsets for many reservoirs, and some datasets have not reported reservoirs and lakes separately. In this study, we generated China's surface water bodies, Large Dams, Reservoirs, and Lakes (China-LDRL) dataset by analyzing all available Landsat imagery in 2019 (19 338 images) in Google Earth Engine and very-high spatial resolution imagery in Google Earth Pro. There were similar to 3.52 x 10(6) yearlong SWB polygons in China for 2019, only 0.01 x 10(6) of them (0.43 %) were of large size (> 1 km(2)). The areas of these large SWB polygons accounted for 83.54 % of the total 214.92 x 10(3) km(2) yearlong surface water area (SWA) in China. We identified 2418 large dams, including 624 off-stream dams and 1794 on-stream dams, 2194 large reservoirs (16.35 x 10(3) km(2)), and 3051 large lakes (73.38 x 10(3) km(2)). In general, most of the dams and reservoirs in China were distributed in South China, East China, and Northeast China, whereas most of lakes were located in West China, the lower Yangtze River basin, and Northeast China. The provision of the reliable, accurate China-LDRL dataset on large reservoirs/dams and lakes will enhance our understanding of water resources management and water security in China. The China-LDRL dataset is publicly available at https://doi.org/10.6084/m9.figshare.16964656.v3 (Wang et al., 2021b).
