| 摘 要： | 蒸散发是水资源分配利用的依据，能够估算出不同气候环境、不同区域的蒸散发是目前研究的重点。这些年运用遥感手段建立模型，结合地面气象站的气象数据、卫星影像等信息，提取参数建立模型来估算蒸散发的方法已经有了较为广泛的运用。其中，利用能量平衡来建立模型尤为广泛，不同的模型，选取参数、处理方法上有所不同，着重针对SEBAL、SEBS估算模型进行详细的对比介绍，SEBAL模型是具有较为坚实的物理基础，已经在平原、盆地、流域等区域进行了成功的应用，SEBS模型与SEBAL模型在模型建立原理上一致，但在计算感热通量H时，采用总体大气的相似理论，引入了热传输粗糙度长度。对这两模型进行了系统学习分析，并针对在新疆未来可开展的工作进行展望。 |

| Abstract: | Evapotranspiration is the basis for the allocation and using of water resources.How to estimate the evapotranspiration in different climate environment and regions is one of the most interesting research fields.In recent years,the methods of estimating the evapotranspiration,in which the model is built by RS,combined with the meteorological datas of weather stations and the satellite images,and built through extracting parameters,is widely used.The model built by energy balance,in which the parameter selection and processing methods are different,is used particularly widely.The comparison of SEBAL and SEBS estimation models is introduced in detail in this paper.The SEBAL model,which has a a solid physical basis,is successfully used in the plain,basins and watershed.Compared with SEBAL model,the SEBS model has the same principle,but the heat transfer roughness length is introduced by using the overall atmospheric similarity theory to calculate the sensible heat flux H.In this paper,the two models are studied systematically and the potential prospect is analyzed. |
