| 摘 要： | 蒸散（发）量是研究农业生产和气象变化的重要内容,而自然陆地区域蒸散（发）量的求取往往比较困难。本文利用Landsat TM/ETM＋卫星遥感资料求出能够体现地表特征的重要参数,遵循陆面能量平衡原理SEBAL,给出了依据研究区特点分为植被覆盖和裸土两种类型的区域蒸散（发）量计算模型。利用该模型对东南沿海城市泉州市的蒸散（发）量进行了反演,并分析了遥感反演模型的特点和该地区蒸散（发）作用的特征,使得区域蒸散（发）量的估算成为可能。 |

| Abstract: | Evapotranspiration is a key factor which frequently used in the agricultural and meteorological change studies.However it is difficult to estimate evapotranspiration(ET) over large area of natural land surface.In this study,the evapotranspiration estimation models with vegetation cover and bare soil were presented based on information of surface parameters like vegetation fraction and surface albedo.Combined with vegetation fraction data,a model for regional evapotranspiration estimation over the heterogeneous landscape was derived from Landsat TM/ETM .Meanwhile,through a case study with remote sensing data in Quanzhou city,which lies in Southeast China,the accuracy of the model for regional evapotranspiration estimation was validated.The features of evapotranspiration in Quanzhou City and models were also discussed.It is possible to estimate the regional evapotranspiration by this model. |
