中国地表太阳辐射分区数据集

中国地表太阳辐射分区数据集包含五个分区（ClassicalFiveZone.tif）和十个分区（ClassicalTenZone.tif）的栅格文件；以及后处理的五分区（BoundaryOfFiveZones.shp）和十分区（BoundaryOfTenZones.shp）矢量文件。分区边界基于时空连续的地表太阳辐射资料和混合高斯聚类模型产生，详细的算法流程可参考文献：Jiang et al. (2021). Hierarchical identification of solar radiation zones in China. Renewable & Sustainable Energy Reviews, 145, 111105.
注意：矢量边界基于栅格数据转换、平滑而来，与标准国界线和海岸线存在分辨率或比例尺造成的差异，使用时国界部分请参照自然资源部标准国界线和海岸线。

The China Surface Solar Radiation Zonation Dataset contains raster files for five-zone (ClassicalFiveZone.tif) and ten-zone (ClassicalTenZone.tif) partitions, alongside post-processed vector boundary files for five zones (BoundaryOfFiveZones.shp) and ten zones (BoundaryOfTenZones.shp). The partition boundaries are generated using spatio-temporally continuous surface solar radiation data and a Gaussian mixture clustering model. The detailed algorithm workflow is documented in the reference: Jiang et al. (2021). Hierarchical identification of solar radiation zones in China. Renewable & Sustainable Energy Reviews, 145, 111105. Note: The vector boundaries are derived from raster data conversion and smoothing operations, and may exhibit discrepancies relative to the standard national boundary and coastline due to resolution or scale differences. When utilizing this dataset, please refer to the standard national boundary and coastline released by the Ministry of Natural Resources of China for the national boundary components.
