Abstract Soil physical and chemical properties of riparian zone, where along Haicheng River in Haicheng city, Liaoning province, at 3 layers of 0～20 cm, 20～30 m, and 30～40 m was studied in this paper. The results showed that the soils were alkaline, and the pH value of different layers is not significant. The physical and chemical properties of upper reaches were preferable. In the middle reaches, values of bulk densities were high, total porocity were low, soil structure were bad, and contents of soil total phosphorus, available phosphorus, organic matter and total nitrogen were especially few because of human interference. Physical properties in the lower reaches were better than that in middle reaches. But some chemical properties were higher because of point pollutions. On the whole, the riparian zone along Haicheng River were serious destroyed, and can't perform its functions such as buffer and improve species diversity.
