Scaling - up of patch model is necessary in the calculation of surface energy fluxes and evapotranspiration from remote sensing data . the simulation error of two - layer model caused by sub - pixel heterogeneity and discontinuity of surface geometry and physics were investigated using a number of data experiments 论文还分析了蒸散模型的空间尺度效应，通过一系列的模拟实验检验了双层模型中国科学院遥感应用研究所博士学位论文在不同地表非均匀状态下的尺度误差，并且根据通量尺度扩展的基本法则推导了双层模型参数的尺度扩展公式。
