2026-07-01 A dataset of ecosystem services in the Dongting Lake Area in 2020 doi:10.57760/sciencedb.cjae.00123 en Dataset Content: This dataset supports the research paper “Ecological Management Zoning of the Dongting Lake Basin Based on Coupling Coordination between Ecosystem Services and Land Use Intensity”. It integrates multi-source spatial data for the year 2020 and comprises four major components:Land use data: Gridded raster data depicting major land cover types (cropland, forest, grassland, water bodies, built‑up areas, etc.) across the Dongting Lake Basin, used to derive land use intensity.Ecosystem service supply and demand data: Estimated supply and demand quantities for key services, including carbon sequestration, water yield, soil conservation, and habitat quality. Data are provided as raster/vector layers, along with summary statistics in Excel (.xlsx) format.Coupling coordination degree: Spatial distribution maps (both annotated and unannotated versions) showing coordination levels between ecosystem service supply–demand matching and land use pressure, calculated using a coupling coordination degree model.Spatial autocorrelation results: Maps illustrating spatial clustering patterns (e.g., Moran’s I cluster maps) of ecosystem service supply–demand and coupling coordination across the basin in 2020, available with and without labels.Spatiotemporal Coverage: The dataset covers the Dongting Lake Basin in Hunan Province (delineated by watershed boundaries), with the reference year set to 2020.Data Formats: Main formats include GeoTIFF (raster), Shapefile (vector), .xlsx (tabular statistics), and .jpg/.png (figures). All spatial data are projected in the CGCS2000 national geodetic coordinate system.Potential Uses: This dataset is valuable for watershed‑scale ecosystem service assessment, land use intensity evaluation, identification of ecological management zones, and studies on the coupling mechanisms between ecological functions and land use. It provides a scientific basis for ecological conservation and territorial spatial planning in the Dongting Lake region.
