| Abstract: | According to the water amount balance principle of irrigation system, a mathematical model of water amount balance in the field is established. The water efficiency of irrigation can be determined by calculating the crop irrigation quota on the theoretical plane and by making use of the water supply statistical data of main water conservancy projects and other water conservancy facilities.A new method for analyzing water efficiency of irrigation districts in {China's} southern region is suggested. |

| Keywords: | irrigation district water resources balance irrigation efficiency |
