Abstract Rice is not only the world's main food crops， but also agricultural water resources of the largest consumer crops. Water use efficiency （WUE） has been a research hotspot of rice resource use efficiency. In this paper， the characteristics of rice leaves and their relationship with water use efficiency （WUE） were summarized from the aspects of WUE concept， leaf structure， leaf chemical composition， leaf hydraulic parameters and leaf photosynthesis， the existing problems were analyzed and the future research directions were prospected.
