China River and Lake Dataset (HydroLAKES v1.0)

HydroLAKES v1.0 is a digital map repository of global lakes, designed to provide comprehensive and consistent lake information at the global scale, covering all lakes with a surface area of at least 10 ha, including freshwater lakes, saline lakes (including the Caspian Sea), as well as human-made reservoirs and regulated lakes. The dataset has a total surface area of 2.67×10⁶km² (1.8% of global land area), a total shoreline length of 7.2×10⁶km (about four times longer than the world’s ocean coastline), and a total volume of 181.9×10³km³ (0.8% of total global non-frozen terrestrial water stocks). As lakes are key components of biogeochemical and ecological processes, this dataset can provide core data support for understanding lake properties and their interactions in the Earth system. The data is open access, and users can refer to alternative datasets such as ReaLSAT and GLOBathy.

HydroLAKES v1.0是一款全球湖泊数字化地图库，旨在全球范围内提供全面且一致的湖泊信息，涵盖所有表面积不小于10公顷的湖泊，包括淡水湖、咸水湖（含里海），以及人工水库和受调控湖泊。该数据集的总表面积达2.67×10⁶平方千米（占全球陆地面积的1.8%），总岸线长度为7.2×10⁶千米（约为全球海洋岸线总长的4倍），总蓄水量达181.9×10³立方千米（占全球非冻结陆地总储水量的0.8%）。由于湖泊是生物地球化学与生态过程的关键组成部分，该数据集可为理解地球系统中湖泊的属性及其相互作用提供核心数据支撑。该数据集为开放获取资源，用户可参考ReaLSAT与GLOBathy等替代数据集。
