| Abstract: | 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. |
