1) forest evapotranspiration
森林蒸散
1.
Based on the measurement of latent evapotranspiration (LE) and sensible heat flux by open-path eddy covariance (OPEC) system, the authors analyzed diurnal and seasonal variations of forest evapotranspiration in the broadleaved_Korean pine forests in Changbai Mountain in 2003.
森林蒸散量日变化特点是白天高于夜间,中午最高,夜间潜热通量和显热通量(H)有低估的现象;季节变化特点是7、8月份蒸散量最高,冬季较低,且蒸散量在净辐射中所占的比例为生长季明显高于非生长季。
2.
Forest evapotranspiration is an important component not only in water balance,but also in energy balance.
以长白山阔叶红松林为研究对象 ,利用长白山阔叶红松林气象观测塔安装的常规气象梯度观测系统、开路涡动相关系统的观测数据 ,依据空气动力学基本理论与能量平衡方程建立了森林蒸散机理模型 ,确定了模型参数 ,即风速廓线稳定度订正函数 φm、温度廓线稳定度订正函数 φh 和零平面位移高度d 。
2) forest evaporation
森林蒸散发
1.
The water surface evaporation and soil evaporation in the forest is not as half out of the forest,and the forest evaporation is calculated according to the material of soil containing water quantity in the forest.
用林内土壤含水量的资料,尝试估算了森林蒸散发。
3) forestland evapotranspiration
林地蒸散
1.
The water consumption of trees in the growing seasons can be reckoned through the evapotranspiration of plants,and the forestland evapotranspiration and water balance can be computed.
2004年5~10月,通过测定青海大通一块退耕地上17年生的青海云杉和华北落叶松混交林树木蒸腾速率的日变化、月变化动态规律以及树木蒸腾总面积来确定混交林的蒸腾量,根据植物的蒸腾量估算树木在生长季的耗水量,进而推算出林地蒸散和水量平衡。
