In this study, based on the Rnl, extinction coefficient k, transition coefficient of canopy layer stomatic resistance K', aerodynamics resistance ra and rc calculated with the data of Rn, LAI, rsi, the daily transpiration variation of Picea purpurea, Larix principisrupprechtii, Hippophae rhamnoides ,Betula platyphylla and Populus cathayana were studied in Datong County, Qinghai Province. Comparing with the practical transpiration variation measured by Li1600 Steady Porometer, the relative error of this model was less than ±15%, and the results were stabilized and tested by precision analysis.

本研究通过对Rn、LAI、rsi的实地观测，确定了林冠截流净辐射、消光系数、冠层阻力转换系数、空气动力学阻力和冠层整体气孔阻力，对青海大通地区紫果云杉、华北落叶松、沙棘、白桦和青杨的日蒸腾过程进行了模拟，与用快速称重法订正的Li1600稳态气孔仪实测蒸腾结果对比，模拟的相对误差在±15%以内；模型敏感性分析发现，温度、LAI以及rsi是决定模拟结果的主要参数，模型对各参数变化反应不敏感。
