摘要
蒸发是鄂尔多斯北部盆地地下水排泄的重要途径,是水资源评价中的一项重要内容。为了计算鄂尔多斯北部盆地的蒸发量,为地下水数值模型的建立提供参数,采用了遥感方法计算蒸发量。应用美国国家海洋与大气管理局的NOAA/AVHRR卫星图像数据,根据SEBS模型计算了研究区的日蒸发量,并用气象站的蒸发观测数据对遥感计算结果进行标定,得到全年的蒸发总量。这种方法使遥感计算蒸发量由科学研究向应用前进了一步。
Evapotranspiration is the primary way of groundwater discharge in the north of the Ordos basin and an important content of water resource assessments. In order to calculate the evapotranspiration amount and provide parameters for the groundwater numerical model, the remote sensing （RS） approach was used for calculation. By adopting the NOAA/AVHRR data from NASA, United States, and according to the model of SEBS, the author calculated the daily evapotranspiration in the study area, and used the observation data from weather stations to calibrate the results of RS calculation and finally got the total yearly evapotranspiration amount. This method promotes evapotranspiration calculation by RS from research to application.
