A phosphorus leaching experiment was performed to study interception of phosphorus in the riparian zone.The removal rate of phosphorus by the soil of the riparian zone is discussed.Results showed that the pH of the simulated rainwater,which acted as leach-water,significantly affected the absorbed phosphorus in the riparian zone soil column.Riparian zone soil column absorbed the minimum TDP and MRP when the rainwater had a pH of 5.The removal rate of the soil of the riparian zone decreased as time went by.Th...
