Spatial inventroy of lake water storage in China

This repository archives the database of in situ measurements of lake depth and storage in China, along with the derived datasets of nationwide freshwater storage distribution and statistics.It contains six datasets: Lake_surveyed, Lake_predicted, Lake_bathymetry, Freshwater_lakes, Freshwater_reservoirs, and Freshwater_watershed.<b>• </b><b>Lake_surveyed: </b>A CSV file documenting 612 lakes with in situ measurements of depth and storage.<b>• </b><b>Lake_predicted:</b> A CSV file for 2,101 lakes not covered by field surveys, where mean depth and storage were estimated using empirical models.<b>• </b><b>Lake_bathymetry:</b> Constructed lake bathymetry in GeoTIFF format for selected representative lakes.<b>• </b><b>Freshwater_lakes:</b> A shapefile showing the distribution of 1,531 freshwater lakes.<b>• </b><b>Freshwater_reservoirs:</b> A shapefile showing the distribution of 5,158 reservoirs (&gt;1 km²) across China.<b>• </b><b>Freshwater_watershed:</b> Spatial distribution of freshwater storage (lakes and reservoirs) at the secondary watershed level.

本仓库归档了中国湖泊水深与蓄水量原位实测数据库，以及衍生的全国淡水蓄水量分布与统计数据集。本数据集共包含六个子数据集：Lake_surveyed（实测湖泊数据集）、Lake_predicted（预测湖泊数据集）、Lake_bathymetry（湖泊水深地形数据集）、Freshwater_lakes（淡水湖泊数据集）、Freshwater_reservoirs（淡水水库数据集）及Freshwater_watershed（淡水流域蓄水量数据集）。
• Lake_surveyed（实测湖泊数据集）：该文件为逗号分隔值（Comma-Separated Values，CSV）格式，记录了612个湖泊的水深与蓄水量原位实测数据。
• Lake_predicted（预测湖泊数据集）：该文件为CSV格式，涵盖2101个未开展野外实测的湖泊，其平均水深与蓄水量通过经验模型估算得到。
• Lake_bathymetry（湖泊水深地形数据集）：针对选定的典型湖泊，构建了GeoTIFF格式的湖泊水深地形数据。
• Freshwater_lakes（淡水湖泊数据集）：该文件为形状文件（shapefile）格式，展示了1531个淡水湖泊的空间分布。
• Freshwater_reservoirs（淡水水库数据集）：该文件为shapefile格式，展示了中国境内5158个面积大于1平方千米的水库的空间分布。
• Freshwater_watershed（淡水流域蓄水量数据集）：呈现了二级流域尺度下的淡水蓄水量（含湖泊与水库）的空间分布特征。
