中巴经济走廊多年冻土分布数据集分为两个文件夹存储，分别为冻土分布栅格图和冻土分布矢量图。前者包括冻土分布栅格图CPEC_PermafrostDistribution2016和冰川分布栅格图CPEC_GlacierDistribution，空间分辨率均是1km,保存格式为tif。后者为多年冻土分布矢量图CPEC_PermafrostDistribution2016，采用SHP格式保存。所有数据地理坐标系为WGS1984。\n
基于遥感数据MODIS地表温度数据产品，利用TTOP模型得到中巴经济走廊多年冻土分布数据（GeoTIFF格式，空间分辨率1km），并采用统计学手段和现有文献资料对数据质量进行分析和评估。\n
本数据集可作为中巴经济走廊多年冻土变化的本底调查资料，为该区域工程建设中冻胀融沉研究提供基础数据支撑。本数据集也可与气候、水文等数据综合分析，揭示中巴走廊喀喇昆仑山区水-土-气-生之间定量联系，深化对该区域气候变化背景下生态环境和可持续发展的科学认识。

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.\r\n
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.
