青藏地区高等级公路沿线道路、桥梁及冻土分布

本数据展示了青藏地区两条高等级公路（青藏公路和共玉高速公路）沿线两侧各十公里缓冲区内不同冻土类型的空间分布情况，以及道路上桥梁的分布情况。冻土分布数据，来源于Zou et al., 2017（https://doi.org/10.5194/tc-11-2527-2017）；桥梁的分布数据基于现场调查资料，通过数字化加工的方式，将其标记于底图上，从而形成本数据。现场调查采用民用手持式GPS，其水平误差值约2~5 m。This dataset depicts the spatial distribution of various permafrost types within 10-kilometer buffer zones on both sides along two high-grade highways (Qinghai-Tibet Highway and Gongyu Expressway) in the Qinghai-Tibet Plateau region, alongside the distribution of bridges on these roads. The permafrost distribution data is sourced from Zou et al., 2017 (https://doi.org/10.5194/tc-11-2527-2017); the bridge distribution data was developed based on field survey records, which were digitized and marked on the base map to generate this dataset. The field survey utilized civilian handheld GPS devices, with a horizontal error of approximately 2–5 m.
