摘要:中巴经济走廊横穿现代冰川广泛分布的喀喇昆仑山和部分帕米尔山区,上游冰川动态及其演化导致的各类冰川相关灾害(冰川洪水/泥石流,冰川跃动,冰缘崩塌/滑坡以及冰川阻塞湖溃决洪水等)在众多山地灾害中尤其突出,对中巴公路及其沿线基础设施、人类活动日益构成威胁。本研究针对中巴经济走廊中国新疆喀什-巴基斯坦伊斯兰堡区段,在充分挖掘已公开发布的各类数据集的基础上,收集了上游冰川作用区的相关灾害调查数据、历史典型灾害事件、跃动冰川信息以及中巴公路沿线的潜在冰川洪水/泥石流沟的空间信息数据,对不同来源的冰川、冰湖相关灾害(事件)数据集进行了汇总整编。数据集包含:(1)中巴经济走廊沿线上游流域分级及冰川、冰湖、水系等基础数据集;(2)跃动冰川分布数据集;(3)冰川堰塞湖历史溃决事件分布数据集;(4)中巴公路沿线冰川洪水/泥石流沟分布数据集;(5)中巴经济走廊沿线上游山体滑坡点分布数据集;(6)中巴经济走廊及周边历史时期地震活动数据集。该数据集可用于中巴经济走廊沿线区域冰川相关灾害风险分析和评估研究,为中巴走廊建设提供基础科学数据支撑,数据集的流域统计结果也可为流域尺度的冰川水资源变化及灾害风险管理提供数据参考。

Abstract & Keywords
Abstract: The China-Pakistan Economic Corridor traverses the Karakoram Mountains and some Pamir Mountains where modern glaciers are widely distributed. The upstream glaciers and their evolution have caused various types of glaciers-related disasters (glacier floods/mudslides, glacier surges, paraglacial collapse/landslides, and ice-dammed lakes outburst floods, etc.) are particularly prominent, and increasingly pose a threat to the China-Pakistan Highway and its infrastructure and human activities. Based on the full excavation of various released data sets, this study collected the relevant disaster survey data, historical typical disaster events, and dynamics of the upstream glaciation area. Spatial information data of glaciers, glacial lakes and potential glacial floods/debris flow catchments along the China-Pakistan Highway have compiled. This dataset includes: (1) upstream watershed classification along the China-Pakistan Economic Corridor and basic background datasets such as glaciers, glacial lakes, and surface stream drainage systems; (2) surge glaciers distribution dataset; (3) distribution of historical outburst events of glacial ice-dammed lakes; (4) Potential glacier flood/debris flow gully distribution along the China-Pakistan Highway; (5) Landslide distribution data set and (6) historical seismicity data. This data set provides a basic scientific data support for the construction of the China-Pakistan Corridor, and can be used for the analysis and assessment of glaciers-related hazards along the China-Pakistan Economic Corridor.
