AB  - The permafrost distribution dataset of the China Pakistan Economic Corridor is stored in two folders: the permafrost distribution raster map and the permafrost distribution vector map. The former includes the frozen soil distribution grid map CPEC_PermafrostDistribution2016 and the glacier distribution grid map CPEC_LacierDistribution, both with a spatial resolution of 1km and saved in tif format. The latter is the vector map CPEC_PermafrostDistribution2016 of permafrost distribution, saved in SHP format. All data are in WGS1984 geographic coordinate system.Based on the remote sensing data MODIS surface temperature data product, the TTOP model was used to obtain the distribution data of permafrost in the China Pakistan Economic Corridor (GeoTIFF format, spatial resolution 1km), and statistical methods and existing literature were used to analyze and evaluate the data quality.This dataset can serve as background investigation data for the permafrost changes in the China Pakistan Economic Corridor, providing basic data support for the study of frost heave and thaw settlement in engineering construction in the region. This dataset can also be comprehensively analyzed with climate, hydrological and other data to reveal the quantitative relationship between water soil air life in the Karakoram Mountains of the China Pakistan Corridor, deepening the scientific understanding of the ecological environment and sustainable development in the context of climate change in the region.
