This data is from the super sample plot of guantan forest station in Dayekou watershed. The arbor vegetation of the super sample plot is pure Picea crassifolia forest, and the sample plot size is 100 m × 100 m. Observation time: 18:00 p.m. from June 1, 2008 to December 31, 2008. If there is rainfall on that day, it will be observed once after the rainfall. If there is penetrating rainfall in the rain collector under lysimeter, the penetrating rainfall shall be measured. Observation location: forest hydrological test plot of Dayekou guantan forest station. Observation contents: 1) In contrast, two rain gauges were observed at the same time, which were set on the flat beach near the hydrological test plot. 2) Through rainfall in the forest, 20 rain gauges were set in the sample plot, which were based on the canopy density above the rain gauges. 3) Lysimeter weight at 18:00 per day. 4) The penetration of rain collectors under lysimeter. Observation instruments: 1) Standard 20 cm diameter rain gauge. 2) Self made lysimeter (20cm in diameter; 4 in total; different soil and vegetation). 3) Electronic balance (accuracy 0.1g) is used to observe the weight change of self-made lysimeter.
The observation data of the sample plot mainly include: Ground-based lidar scanning data, total station positioning measurement data, differential GPS positioning measurement data, tree survey data, leaf area index observation data, canopy spectral measurement data, canopy camera observation data, soil evapotranspiration data, soil freezing pipe observation data, surface roughness data, rainfall interception data, soil moisture observation data Soil moisture measurement data, dry and wet weight measurement data of forest components, etc.
The weight difference before and after observation was used to calculate the soil water evaporation combined with the water density and lysimeter diameter (20cm).
