| Abstract: | On the basis of water-saving irrigation technigue code and concrete situation of Shanxi Province,the different target values of water efficiency of canal system are determined and the water-saving potential values of canal seepage control are estimated thereby.According to the relationship between the water efficiency of canal system and present situation of canal seepage control,the length of stationary canal on which the seepage control measures must be adopted and the length of seepage control canal that must increase are estimated to attain the different target values of water efficiency of canal system. |

| Keywords: | canal seepage control water efficiency of canal system target value water-saving potential |
