摘要
作为中国典型粮食主产区,河北省水资源短缺是制约其作物产量的关键因素,提高耕地粮食作物用水效率是保障区域粮食安全和实现农业可持续发展的核心。作者基于气象数据、联合国粮农组织CROP数据库数据、实地调查数据及农村统计年鉴数据,借助超效率SBM模型、空间计量模型和GTWR模型,计算了河北省139个县域单元1995–2019年在多要素投入产出框架下的粮食作物用水效率数据集。数据集包括:(1)研究区范围;(2)1995、2000、2005、2010、2015、2019年粮食作物蓝水、绿水及灰水足迹数据;(3)1995–2019年粮食作物水足迹变动趋势数据;(4)1995、2000、2005、2010、2015、2019年县域和分区两种尺度粮食作物水分利用效率数据;(5)粮食作物水分利用效率影响因素的空间效应、溢出效应及空间异质性数据;(6)冀西北区、沿海区、环京津区、冀中南区的泰尔系数与贡献率。数据集存储为.xlsx和.shp格式,由65个数据文件组成,数据量为4.09 MB(压缩为1个文件2.36 MB)。
Water scarcity is a crucial factor limiting crop yields in Hebei Province,which is a typical grain-producing region in China.Improving the efficiency of water use of grain crops on farmland is essential for ensuring regional food security and achieving sustainable agricultural development.Author base on dataset of the efficiency of water use of grain crops in Hebei Province of China(1995–2019)was developed by integrating data from the meteorological database of China,the United Nations Food and Agriculture Organization's(FAO)CROP database,field surveys,rural statistical yearbooks,and the super-efficiency SBM model,spatial econometric model,and GTWR model.The dataset contains the following:(1)data on boundaries of the study area;(2)data on the blue water,green water,and gray water footprints of grain crops in 1995,2000,2005,2010,2015,and 2019;(3)data on the trends of changes in the water footprints of food crops from 1995 to 2019;(4)efficiency of water use of grain crops at the county and regional scales in 1995,2000,2005,2010,2015,and 2019;(5)spatial effects,spillover effects,and spatial heterogeneity of the factors influencing the efficiency of water use of grain crops;and(6)the Theil coefficient and the rates of contribution of the four partitions.The dataset has been archived in.xlsx and.shp data formats,and consists of 65 data files with a total size of 4.09 MB(compressed into one file with a size of 2.36 MB).
