| Abstract: | Water use efficiency of irrigation district is an important index indicating the extent of water use efficiency of irrigation. The connotation of water efficiency of irrigation is introduced, and the traditional method estimating water efficiency of irrigation is expatiated. Through analysis of the problems and difficulties of traditional method, simplified estimation methods for water efficiency of irrigation using net crop irrigation water quota, annual net comprehensive irrigation water quota and the production of irrigation district are proposed and discussed. |
