The distribution data of permafrost in the source area of the Yellow River is established based on the annual average ground temperature model of permafrost in the source area of the Yellow River. The annual average ground temperature of 0 ℃ is taken as the standard and boundary for dividing seasonal frozen soil and permafrost. Compared with the available permafrost maps of the source region of the Yellow River (1:3 million) and the permafrost background survey project of the Qinghai Tibet Plateau (1:1 million), the data set is based on the measured data of the Yellow River source area, which has higher consistency with the measured data, and the simulation accuracy of the permafrost distribution map is the highest. The data set can be used to verify the distribution of permafrost in the source area of the Yellow River, as well as to study the frozen soil environment.

File naming and required software

Data of permafrost distribution range, seasonal frozen soil sub range and lakes in the source area of the Yellow River. Don't store the vector file separately in the folder. The data format is ". SHP", and the name of the file is "permafrost distribution data. SHP" in the source area of the Yellow River. It can be opened with ArcMap of ArcGIS platform version 10.3 or above.
