\nThe data of this data set mainly include: control atmospheric rainfall, through rainfall in the forest, trunk flow, through rainfall of moss and litter barrel. The data can be used to study the canopy interception characteristics of Qinghai Spruce and develop the rainfall interception model of Qinghai Spruce. The two rainfall tubes for observation and control of atmospheric rainfall are located on a flat beach near the hydrological test sample plot, and are observed in time after each rainfall. 20 rain cones penetrating rainfall in the observation forest are arranged in sub plot 3 of super sample plot. The layout rules of rain cones are based on the canopy canopy density directly above. In the sample plot, nine self-made rain tanks were arranged according to the regular grid to observe the penetrating rainfall in the forest. The observation of stem flow is to record the rainfall collected by the rain collector in the self-made stem flow device.
