This data comes from the super sample plot of guantan forest station in Dayekou basin. The tree vegetation of the super sample plot is pure Qinghai Spruce Forest, and the sample plot size is 100m × 100m。 The data set is the data of soil freezing depth, which is to study the daily change process of soil freezing depth in Qinghai Spruce Forest. The soil freezing pipe is located in Dayekou guantan forest station and is arranged under Qinghai Spruce Forest next to the automatic weather station.
From June 1, 2008 to December 31, 2008, observe the daily freezing depth at 8:00 every morning. The recorded contents include the upper and lower freezing limits of each layer. There is no stratification phenomenon in soil freezing in this sample plot, so there is only the upper freezing limit of one layer. The unit of observation data is cm, and 1 decimal place is recorded
