摘要:

为解决气象栅格数据与社会经济行政单元存在的尺度错位问题,本研究整合MERRA-2再分析资料与多源人口普查数据,研发了中国极端高温热浪人口暴露数据集(2000、2010、2020)。该数据集采用5年滑动平均窗口剔除年际气候噪音,基于相对与绝对阈值相结合法识别热浪事件,并通过人口加权与区域统计将连续气象格点降维映射至中国367个行政单元。数据集内容涵盖了2000年、2010年及2020年三个关键时点的人口热浪暴露频次、暴露时长及累积热负荷等多维指标。精度验证显示,源数据MERRA-2与地面观测气温一致性极高(R²>0.97),数据集提取的热浪频次与35个重点城市实测值相比,均方根误差(RMSE)仅为0.89次,数据质量可靠。数据集存储为.xlsx和.shp格式,共计9个数据文件,数据量为27.1 MB(压缩为1个文件,17.8 MB)。该数据集支持了学位论文科学发现。
