黄河流域主要水文参数遥感反演

Key hydrological parameters retrieved by using remote sensing technique in the Yellow River Basin

以土壤、大气和植被系统(SPAC)能量流动与物质转换机理为指导,建立了黄河流域主要水文参数的遥感反演模型,利用静止气象卫星GMS 5和风云2号数据,对黄河流域的降水量、蒸散量进行了反演,利用地面资料对降水量反演结果进行了校验;利用大孔径闪烁仪对蒸散量反演结果进行了多方位的验证。

Guided by the theories on energy flowing and materials exchange within Soil-Atmosphere-Plant Continuant (SPAC), retrieval models of key hydrological parameters were established in the Yellow River Basin based on remote sensing technique The precipitation and evapotranspiration were derived from the meteorological satellite GMS-5 and Fengyun-2 meteorological satellite data A precipitation model is calibrated and tested with the ground observed data; meanwhile, the evapotranspiration result is verified with the large aperture scintillometry 
