For the rational use of ground-water and the determination of proper well number of the people's victory canal irrigation,the well-canal irrigation proportion was determined by using the balance of supplement-exhaust on the basis of the ground-water evaluation.Then the amount of pump well was determined by using the method of the single well control area and the exploitation modulus.The results showed that the amount of planned pump well was 14 553 wells,and 5 708 wells should be cut down.
