摘  要：
In order to manage and utilize irrigation water resources scientifically and reasonably by using evapotranspiration( ET)- based strategy,the development of ET estimation theories and methods were reviewed,and firstly,models for regional ET estimation were summarized systematically; secondly, the basic principle for ET estimation based on RS data and surface energy balance models were elaborated,as well as the applications about the models in optimal allocation and management of irrigation water resources were expounded; finally,the problems existing in ET estimation based on RS were analyzed and the trends were prospected. It's a necessary and feasible approach to estimate ET based on RS and manage irrigation water resources by using ET-based strategy,and the approach has an important theoretical guidance and practical significance for developing modern water-saving agriculture,as well as planning and managing irrigation water resources scientifically.
