蒸散发是水分循环的重要环节,影响着作物生长和粮食生产,获得长时序高空间分辨率蒸散发过程数据有助于优化区域水资源配置。基于lands.t和MODIs.感数据,结合地面观测通量数据和气象数据,利用s.Bs.型和Es.ARFM模型获得了南方红壤区2019年4−10月高时空分辨率日蒸散量,并分析高时空分辨率日蒸散量时空变化特征及其影响因素。结果表明:高空间分辨率的遥感影像可获得精度更高的遥感蒸散模拟效果,基于lands.t遥感数据驱动的s.Bs.型的模拟效果优于基于MODIs.感数据作为输入的s.Bs.型。Es.ARFM模型获得的高时空分辨率日蒸散量与实测蒸散量对比,RMs.为0.68mm·d^(−1),R^(2)为0.87。模拟获得的2019年4−10月高时空分辨率日蒸散量在空间变化上与土地利用类型相关。各土地利用类型的蒸散量表现为林地>稻田>其他农用地,在时间变化上,4−8月蒸散量呈上升趋势,8−10月蒸散量则逐渐降低,气温是影响研究区域蒸散量的主要气象因子。基于s.Bs.型和Es.ARFM模型获得的高时空分辨率蒸散量与实测蒸散量具有良好的相关性,s.Bs.型与Es.ARFM模型结合的方法可作为估算南方红壤区蒸散量的有效工具。
