Abstract：According to irrigation-drainage systems,the multi-water cycle and transformation model were estab-lished in accordance with the local specifications in the People's Victory Canal Irrigation District in this study. The average annual transforming relationships of multi-water resources were then simulated in the system of wa-ter intake,conveyance,distribution and drainage,successively.The results showed that the established model was feasible and could simulate the processes of multi-water cycle and transformation well.Water transformation mainly occurred in the water conveyance and distribution system,with 176 million and 966 million m3 water re-sources for transformation respectively.While only 1 million and 13 million m3 water resources were transferred in the water intake and drainage system respectively.It was found that leakage was the main way of water trans-formation in the water intake system,which could increase the risk of soil secondary salinization and waterlog-ging damage along the conveyance channels.Due to the backward irrigation modes,the farmland leakage ac-counted for 28%of water transformation in the water distribution system.
