摘　　要：农田灌溉高效用水管理对农业生产及水资源可持续利用至关重要。气候变暖和社会经济发展对农业水资源的可持续利用带来重大挑战,农业生产集约化、标准化和信息化对发展高效节水灌溉、实现灌溉用水精细化管理提出了更高的要求。蒸散发可反映地表与大气的水分和能量交换以及作物耗水,在灌溉用水管理中发挥着关键作用。过去20年来随着遥感对地观测技术不断发展,蒸散发遥感反演和数据融合理论方法不断成熟,数据的时空分辨率和精度不断提升,显著扩展了遥感蒸散发在灌溉用水管理中的应用范围,在灌溉用水量估算等领域得到深度应用。本文在概述国内外蒸散发遥感反演和数据融合研究前沿及相关数据集的基础上,重点对遥感蒸散发在灌溉用水量估算、灌溉制度优化和灌溉效益评价等三个方面的应用场景,进行了系统梳理和总结,以期为农业水资源高效利用和精细化管理提供参考。High-efficient usage of irrigation water resources is essential to ensure agricultural production and sustainable utilization of water resources.Climate warming and rapid socio-economic development pose great challenges to the sustainable use of irrigation water resources.Current agricultural production tends to be more intensive,standardized and informationized,resulting in higher requirements for the development of efficient water-saving irrigation and the realization of precision management of irrigation water use.Evapotranspiration can reflect the exchanges of water and energy between the surface and the atmosphere and water consumption by crops,thus playing a key role in irrigation water management.Over the past two decades,with the development of Earth observation technologies,theories and methods of remote sensing retrieval of evapotranspiration and data fusion are becoming mature,resulting in continuously improving spatiotemporal resolution and accuracy of evapotranspiration estimates.This trend has greatly maximized the application potential of remotely based evapotranspiration in the field of irrigation water resources.First,this review summarizes the advances of remote sensing retrieval of evapotranspiration and data fusion and related widely used datasets.Applications of evapotranspiration in irrigation water use monitoring,irrigation schedule optimization,and evaluation of irrigation benefits are systematically summarized.This review could provide reference for efficient utilization and precise management of agricultural water resources.
