%X This data comes from the super sample plot of guantan forest station in Dayekou basin. The tree vegetation of the super sample plot is Qinghai Spruce, and the sample plot size is 100m × 100m. The observation data for the sample plot mainly include: Ground Lidar scanning data, total station positioning measurement data, differential GPS positioning measurement data, tree survey data, leaf area index observation data, spectral measurement data, canopy camera observation data, soil evapotranspiration data, soil freezing tube observation data, surface roughness data, rainfall interception data Soil moisture measurement data, dry and wet weight measurement data of forest components, etc. The forest hydrological test sample plot is a sub sample plot of the super sample plot, with a size of 25m × 25m。 In order to study the rainfall interception characteristics of Qinghai Spruce under different canopy density, we took photos of the canopy with an ordinary digital camera in the hydrological test sample plot of guantan forest station in Dayekou basin. A total of 32 groups of photos were obtained in the test plot. Through the analysis of these photos, we can determine the structural information of the canopy. According to the canopy closure information, we determine the number and final location of rain tubes arranged in the hydrological test sample plot. Through the subsequent processing, we can accurately determine the canopy closure corresponding to the canopy above the rainfall tube arranged in the hydrological test sample plot. Observation time: 9:00-10:40, June 4, 2008. Observation site: hydrological test plot of guantan forest station in Dayekou basin. Observation content: canopy photo corresponding to rainfall tube.Observation instrument: ordinary digital camera (Pentax k100d). Resolution: 2400 × 1600。  Observation purpose: to calculate the canopy canopy closure corresponding to the rainfall tube
