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纯林，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、冠层光谱测量数据、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
\n该数据主要用自制的Lysimeter来观测青海云杉林林内的土壤蒸散发特征。 为流域蒸散发模型的发展提供基础数据，为遥感反演蒸散发提供地面验证数据。\n
\n观测时间：2008-06-01至2008-12-31日每天下午18:00，如果当天有降雨的话，会在降雨结束后观测一次。 利用观测前后的重量差值，然后结合水的密度和Lysimeter的直径（20cm）来计算土壤水分蒸发量。 若Lysimeter下的集雨器内有透过雨量，则要测量该透过雨量。 观测地点： 大野口关滩森林站森林水文试验样地。 观测内容：1）对照的大气降雨，有两个雨量筒同时观测， 布设在水文试验样地附近平缓的河滩上。 2）林内穿透降雨，在样地内共布设了20个雨量筒，布设的依据是雨量筒上方的冠层郁闭度。 3）每天18:00的Lysimeter重量。 4）Lysimeter下面集雨器的透过雨量。\n
\n观测仪器：1）标准20cm直径雨量筒量雨器。2）自制Lysimeter（直径20cm；共4个；土壤植被各不相同）。3）电子天平（精度0.1g），用于观测自制Lysimeter的重量变化。

\nThis data mainly uses the self-made lysimeter to observe the characteristics of soil evapotranspiration in Qinghai Spruce Forest. It provides basic data for the development of watershed evapotranspiration model and ground verification data for remote sensing inversion of evapotranspiration.\n
\nObservation time: 18:00 p.m. every day from June 1, 2008 to December 31, 2008. If there is rainfall on that day, it will be observed once after the rainfall is over. The weight difference before and after observation is used, and then the soil water evaporation is calculated in combination with the water density and lysimeter diameter (20cm). If there is transmitted rainfall in the rain collector under lysimeter, the transmitted rainfall shall be measured. Observation site: forest hydrological test plot of Dayekou guantan forest station. Observation contents: 1) for the control atmospheric rainfall, two rainfall tubes are observed at the same time and arranged on the flat river beach near the hydrological test sample site. 2) Through rainfall in the forest, a total of 20 rain cones are arranged in the sample plot, which is based on the canopy canopy canopy density above the rain cones. 3) Lysimeter weight at 18:00 every day. 4) The rainfall transmitted by the rain collector under lysimeter.\n
\nObservation instrument: 1) standard 20cm diameter rain gauge. 2) Homemade lysimeter (diameter 20cm; 4 in total; Soil vegetation varies). 3) Electronic balance (accuracy 0.1g) is used to observe the weight change of self-made lysimeter
