基于《中国冰雪冻土图》的中国冻土分布图

该数据集对扫描图《中国400万冰雪冻土图》（施雅风、米德生，1988）进行几何校正，然后通过数字化，综合考虑海拔和纬度，结合多年冻土的连续性将冻土划分为：高纬度多年冻土的大片多年冻土、岛状融区多年冻土和岛状多年冻土；高海拔多年冻土和高山多年冻土（包括阿尔泰山，天山，祁连山、横断山、喜马拉雅山及中国东部的太白山、黄...

This dataset first performs geometric correction on the scanned map *Map of China's Frozen Soil and Snow Cover at 1:4,000,000 Scale* (Shi Yafeng, Mi Desheng, 1988), followed by digitization. Taking altitude and latitude into comprehensive consideration and combining with the continuity of permafrost, frozen soil is classified into: continuous permafrost, talik-bearing island permafrost and isolated island permafrost in high-latitude permafrost regions; high-altitude permafrost and alpine permafrost (including the Altai Mountains, Tianshan Mountains, Qilian Mountains, Hengduan Mountains, Himalayas, as well as Taibai Mountain, Huang... in eastern China)
