黄土高原1992-2020年1000m分辨率产水服务数据集
A dataset of 1,000 m resolution water production services on the Loess Plateau(1992-2020)
摘要
Abstract
Based on the VIC(Variable Infiltration Capacity)hydrological model,this dataset integrates multi-source remote sensing surface parameters,meteorological reanalysis data and soil data to construct a spatiotemporally continuous dataset of 1,000 m resolution water production services on the Loess Plateau from 1992 to 2020.The study area covers the five major river basins of the Loess Plateau(33°39′0"-42°0′0"N,98°31′12"-113°38′24"E),with a total area of about 623,000 km2.The dataset quantifies the spatiotemporal patterns of water production services and the hotspots of supply-demand imbalance before and after the implementation of the project through a rasterized supply-demand ratio algorithm.Data processing was performed using ArcGIS spatial analysis and Fortran programming,and model validation was conducted at three representative hydrological stations:Lanzhou,Toudaoguai,and Huaxian.The Nash efficiency coefficient(Ens)of the three stations exceeded 0.74,of which the Nash efficiency coefficient(Ens)of the three stations reached 0.744 in the regular(1992-2006)rate of Huaxian station,and increased to 0.872 during the verification period(2007-2020),and the relative error(Er)was less than 3.4％.The model shows high simulation accuracy under different hydrological and climatic conditions on the Loess Plateau.The dataset contains 29 years of water production service raster data(TIF format and nc format),with a data volume of 9.06 MB,characterized by long-term temporal continuity,spatial clarity and process traceability.The dataset can be used for the assessment of hydrological effects of ecological engineering,the analysis of vegetation restoration and water resource carrying capacity,the prediction of the vulnerability of water production services under climate change scenarios,and the optimization of ecological restoration planning,providing high-precision data support for the ecological governance of the Yellow River Basin and for adaptive management of human-land systems in semi-arid areas worldwide.关键词
