Abstract：To reveal the impact of human disturbance on the riparian zone soil, the riparian zone of Xi River, where is frequently disturbed by human in recent years, and is located in Benxi City, Liaoning Province, has been selected as the research object. By using field investigation and laboratory analysis methods, the soil physical and chemical properties of the 27 points at three different sampling depths of 0—20cm, 20—30cm, and 30—40cm were studied. The results indicate that the riparian zone soil of Xi River has a hard soil matrix and a poor soil structure. The values of bulk densities are generally high, and total porosity of that is generally low. The soils are neutral or alkalescent. Contents of soil total phosphorus are generally high; however, the available phosphorus is extremely low. The value of organic matter and total nitrogen is very different in different points, and there is a significant relationship between the two properties. In the general, the property values in different points is significantly different, however it is insignificantly different among the three different sampling depths at the same point. Research results show that the frequent human interference with the riparian zone soil of Xi River has the serious influence on the soil natural layer, and the restoration process for the zone needs a long period.
