摘　　要：在对SEBS模型的有关参数进行订正的基础上,利用MODIS遥感数据结合地表气象观测数据,对黄淮海地区地表能量通量进行了估算。将SEBS估算结果先与北京顺义定量遥感综合试验(QRSLSP/Shunyi)实测结果进行对比分析,然后与郑州的大孔径闪烁仪(LAS)观测的感热通量进行对比分析。结果表明,SEBS估算的通量与二者的实测结果相当一致。因此,利用改进后的SEBS模型估算的黄淮海地区地表能量通量具有一定的精度,可满足区域日蒸散量计算等的需求。After calibrating the model of SEBS （surface energy balance system） according to the in-situ parameters in the study areas, the land surface fluxes over the Yellow-Huaihe-Haihe River regions in northern China has been estimated by using MODIS data and meteorological observations. The estimated fluxes by using SEBS in clouds free days are first compared with the measurements from QRSLSP/Shunyi Campaign near Beijing （Liu et al. 2002） and then compared to the measurements by Large Aperture scintillometers （LAS） in Zhengzhou LAS station located in Henan Province, China. Both the comparisons show that the estimated fluxes from SEBS have a good agreement with the measurements and the results showed that this method can be applied to map the land surface eavaportranspiration in monitor the estimated fluxes have the enough accuracy to deriving the evaportranspiration in regional scale.
