全国湖泊型流域综合数据集（1980-2020年）

为方便相关用户获取中国湖泊流域综合数据，CODCLAB被组织为3种数据格式，包括栅格数据文件（一级）、矢量数据文件（二级）和表格统计数据文件（三级）。一级数据产品包含了CODCLAB的原始静态或时间序列栅格数据文件，例如地形、气候、人文因素等数据子集；分配给湖泊型流域的流域尺度特征存储在流域边界的二级矢量文件中，如湖泊供给系数等。所有湖泊-流域属性都在与湖泊ID关联的第三级表格中提供，它存储了包括湖泊ID、人口密度、GDP等人文要素主导的信息。
CODCLAB数据集完整地提供了全国湖泊型流域的地理边界，是重要自然地理对象的本底信息；同时以湖泊流域为空间约束汇编的自然-人文综合多要素数据产品将为相关科学研究提供数据支撑，并期望服务不同应用部门的监测管理和决策分析需要。
该数据集主要为三级数据产品，即excel表格格式数据

To facilitate relevant users in accessing comprehensive data on China's lake basins, CODCLAB is organized into three data formats: raster data files (Level 1), vector data files (Level 2), and tabular statistical data files (Level 3). Level 1 data products include original static or time-series raster data files of CODCLAB, such as data subsets of terrain, climate, and human factors; basin-scale features allocated to lake-type basins are stored in Level 2 vector files of basin boundaries, such as lake supply coefficients. All lake-basin attributes are provided in Level 3 tables linked to lake IDs, which store information dominated by human factors including lake ID, population density, and GDP.
CODCLAB dataset fully provides the geographic boundaries of national lake-type basins, serving as the background information for important natural geographical objects; meanwhile, the comprehensive multi-factor data products integrating natural and human elements compiled with lake basins as spatial constraints will provide data support for relevant scientific research and are expected to serve the monitoring, management, and decision-making analysis needs of different application departments.
This dataset mainly consists of Level 3 data products, i.e., data in Excel table format.
