Abstract：Jiefangzha irrigation field in Hetao Irrigation District is taken as the background, the changes in water and salt in the salt wasteland of the field are studied. Based on field experiments, the salt wasteland area is summarized through interpreting TM data acquired by remote sensing technology, then salt accumulation and loss in the soil of the wasteland are simulated and analyzed by using HYDRUS-1D model. The results show that the salt wasteland has covered 16.32% of the 2 156.47 km2 total area of the field and salt is mainly accumulated in the soil surface layer. The salt accumulation in the salt wasteland is 10.32?106 kg in the 1m deep soil layer during the whole growth period of crop. The loss of salt in autumn irrigation is 9.60?106 kg, which accounts for 93.01% of the total salt accumulation. The annual salt accumulation is 0.72?106 kg, 6.99% of the total salt accumulation. Upon inspection, the HYDRUS-1D model can simulate the vertical migration of soil water and salt with high accuracy, representing the law of salt accumulation and loss. The accumulation and loss of salt in wasteland plays an important regulating role in salt in the soil of irrigation field. The results can provide a scientific basis for study on water and salt migration in an irrigation field.
