摘　　要：地表蒸散研究一直受到水文、气象、水利、生态、农学等相关学科的高度关注,其分割结果更是水文计算、灌溉管理、产量估测、土壤水分预报及工程设计的基础与依据。从地表蒸散总量及其分量的测定方法出发,对目前国内外关于地表蒸散及其分量的测定方法进行了全面地评述,在此基础上介绍了地表蒸散的分割方法及其最新研究进展,并提出了地表蒸散测定及其分割方法在研究中存在的问题和未来发展方向。Surface evaportranspiration has always been highly valued by hydrology,meteorology,hydraulic engineering,ecology,agronomy and other related disciplines.The results of partitioning ET are considered as the foundation of hydrological calculation,irrigation management,yield estimation,soil moisture forecast and engineering construction.This paper starts from the view of determination methods of ET,E and T,and makes a comprehensive review of research progress about evaportranspiration partitioning methods and their latest research progress at home and abroad.Finally,it puts forward the problems and directions of evaportranspiration determine and partitioning methods in the future.
