摘要
为提供陕西关中地区水资源配置和开发利用的合理依据,亟需对关中地区未来主要气象因素进行分析和预报,研究蒸散发量的时空变化是关键。基于近50年7个气象站点资料,应用加拿大互补相关模型(CRAE)计算分析了关中地区实际蒸散发量的年内变化与其影响因素,获得了实际蒸散发量年内变化与气象因素变化的特点及影响实际蒸散发量变化的气候要素的变化趋势。
To provide a reasonable basis of water resources allocation and development of Guanzhong region in Shanxi Province, it is urgent to analyze and forecast the future meteorological factors in Guanzhong region. And study of the temporal and spatial variation of the evapotranspiration is the key. Based on the data of 7 meteorological stations in nearly 50 years, the annual change and influence factors of the actual evapotranspiration in Guanzhong region are analyzed by using the Canada complementary relationship areal evapotranspiration model （CRAE model）. The variation characteristics of annual areal evapotranspiration and meteorological factors are obtained. And the change trend of the influence climate factors is also gotten.
