本数据来自大野口流域关滩森林站超级样地，该超级样地乔木植被为青海云杉，样地大小为100m×100m. 针对该样地的观测数据主要有：地基激光雷达扫描数据、全站仪定位测量数据、差分GPS定位测量数据、测树调查数据、叶面积指数观测数据、光谱测量数据、冠层的相机观测数据、土壤蒸散发数据、土壤冻结管观测数据、地表粗糙度数据、降雨截留数据、土壤水分测量数据、林木组分干湿重测量数据等。\n
森林水文试验样地属于超级样地的一个子样地，大小为25m×25m。为了研究青海云杉在不同冠层郁闭度下的降雨截留特征，在大野口流域关滩森林站水文试验样地，我们用普通数码相机对冠层进行了拍照。在试验样地内共得到了32组照片。通过对这些照片的分析，我们可以测定冠层的结构信息，根据郁闭度信息我们确定了该水文试验样地布设的雨量筒数量和最终的位置。通过后续的处理，我们可以比较精确的确定水文试验样地内布设的雨量筒上方冠层对应的郁闭度。 \n\n

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.\n
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.\n
