| 摘 要： | 蒸散是水资源管理的一个重要参数。与传统的蒸散计算方法相比,利用遥感进行蒸散研究具有快速、准确、大区域尺度及地图可视化显示等特点。本文通过研究,提出了基于能量平衡方法遥感反演蒸散发的计算模型,指出了模型参数的求解方法,建立了基于MOD IS遥感数据的大区域蒸散发遥感反演技术方法。通过对石羊河流域进行试验,反演误差基本小于10%,并且具有进一步推广的技术前景。

| Abstract: | Evapotranspiration(ET) is an important parameter for water resource management.Compared with the traditional ET computation methods,the ET computation method based on Remote Sensing has the characteristics of quickness,precision,large-scale and visualization mapping.The evapotranspiration estimation model is presented based on energy balance through remote sensing in this paper,The parameters of the model could be modeled using empirical and semi-empirical formulas.Through a case study in ShiYang River Valley,it is proved that this model has a strong practicality.The method provides a precise and efficient way for Retrieving evapotranspiration based on remote sensing and it has showed a great potential in this field. |
