| 摘 要： | 根据渭河流域20个气象站1959～ 2008年逐日气象资料,以FAO Penman-Monteith法计算的各站逐日潜在蒸散量作为标准值,对基于气温的Hargreaves法进行参数校正以使其适用于渭河流域.应用统计降尺度模型SDSM将HadCM3输出数据降尺度到各站点,生成A2,B2两种情景下各站未来日最高、最低气温数...

| Abstract: | The parameters in the temperature-based Hargreaves method for the estimation of potential evapotranspiration(ETP) are calibrated by the FAO Penman-Monteith method and daily data during the period 1959-2008 at 20 meteorological stations in the Weihe River basin.To study the impact of climate change on potential evapotranspiration,the projected daily maximum and minimum air temperature(Tmax/Tmin) of HadCM3 GCM under A2 and B2 scenarios are first downscaled onto local meteorological stations using the statisti... |
