中巴经济走廊1km分辨率冰冻圈关键参数数据集（2001-2020）

从全球范围的季节性积雪、山地冰川、冻土和土壤冻融产品提取出中巴经济走廊带地区冰冻圈关键参数产品，结合中巴铁路等线形工程建设参考标准，应用现有青藏高原和中巴合作资料，研发中巴经济走廊新产品。本产品作为中巴铁路等线形工程建设参考标准，为“一带一路”战略实施提供数据基础。

Key cryospheric parameter products targeting the China-Pakistan Economic Corridor (CPEC) zone were extracted from global-scale seasonal snow cover, mountain glacier, permafrost, and soil freeze-thaw datasets. Combined with reference standards for linear engineering construction such as the China-Pakistan Railway and utilizing existing data from the Qinghai-Tibet Plateau and China-Pakistan collaborative research, new tailored products for the CPEC zone were developed. These products serve as reference standards for linear engineering construction including the China-Pakistan Railway, providing a critical data foundation for the implementation of the Belt and Road Initiative (BRI).
