Abstract In order to solve the problem of freshwater shortage, utilize water resource sustainably in arid and semiarid region, and make the best use of saline water in shallow ground water, saline-fresh water alternately continuous infiltration, contrast with all freshwater and all saline water, was taken to study the water-salt distribution in soil profile and soil physicochemical properties. It showed that, the alternate sequence affected the formation of the macropores and lead to the difference of water permeability of soil, the amount of salt which comes from irrigation water is the main factor of soil salt; the extension of irrigation time help to improve the desalting depth of soil profile, the infiltration sequence fresh-saline-saline is the best to salt-leaching effect; it makes the sodium adsorption ratio in 20 cm depth increase under each kind of fresh-saline water combination, the soil permeability will be decreased especially infiltrated all by saline water, it will probably lead to the soil secondary salinization, this study provides an basis to the reasonable utilization of saline water.
