Economic spatial distribution data serve as an indicator for disaster loss assessment. The economy of the Qinghai-Tibet Plateau is relatively backward and geological disasters occur frequently, so it is of great significance to study the impact of disasters on the economy in this area. Based on the method of zoning and industry simulation, this study establishes the corresponding relationship between the GDP1(GDP of Primary Industry)and land use types, DEM(Digital Elevation Model), village points, roads and river buffers. Spatial models of night lighting, building site and points of interest data after the coupling of the GDP23(GDP of Secondary and Tertiary Industries)and multiple information are established in urban areas and counties. We used the random forest to determine the weights of various indicators in the secondary and tertiary industries, and calculated the grid value of GDP23. Finally, we superimposed the grid of GDP1 and GDP23 and created the spatial distribution map of GDP(Gross Domestic Product)of 100 m×100 m on the Qinghai-Tibet Plateau in 2020. According to the accuracy verification using county-level GDP statistical data, the Root Mean Square Error is 0.0385, which shows that the data can better reflect the spatial distribution of GDP on the Qinghai-Tibet Plateau. This dataset can provide GDP spatial data support for disaster risk assessment, disaster prevention and mitigation on the Qinghai-Tibet Plateau.
海北藏族自治州(以下简称海北州)位于青海省东北部,是青海省发生地震较多的区域之一.在地震中,建筑物作为最重要的承灾体底数之一,数据比较缺少.作者基于欧空局的10 m分辨率的土地利用数据和阿里云的AI Earth平台2020年7月高分辨率影像,研发得到青海省海北州建筑物空间分布数据集(2020).该数据集存储为.shp 格式,由8 个数据文件组成,数据量为9.18 MB(压缩为1 个文件,3.55 MB).
