Dahei River Basin Long-term Water Environment and Human Geography Dataset

This dataset comprises multi-source data for the Dahei River Basin, a typical tributary of the Yellow River in China. It integrates long-term time series of water environment variables (e.g., water quality parameters, pollutant concentrations), socio-economic indicators (GDP, population density), land use/land cover classifications, and meteorological and hydrological station observations (e.g., precipitation, temperature, streamflow). The data span multiple years (e.g., 2000–2020) and are available in various formats including tabular data (CSV), raster grids (GeoTIFF), and vector files (Shapefile). Data sources include government statistical yearbooks, remote sensing imagery (e.g., Landsat), and in-situ measurements from meteorological and hydrological stations. This comprehensive dataset supports research in integrated watershed management, hydrological modeling, environmental impact assessment, and the analysis of human–nature interactions in arid and semi-arid regions.
