Based on 69 soil sample data, soil features, spatial pattern and the environmental factors were analyzed with multiple statistical methods. Results showed that water content, content of soil porosity, total phosphorus, organic matter and total nitrogen decreased significantly from upper layer to lower layer; while pH, active phosphorus and bulk density changed irregularly. All soil samples could be clustered into 2 types according to their physical and chemical characteristics: one type distributing mainly in the main stream and branches in the upper part of basin showing slight acidity and high organic and total nitrogen content; and the other type distributing mainly in the middle and lower part of basin with slight alkalescence and low organic matter and total nitrogen. Redundancy analysis showed that altitude, annual precipitation, annual average temperature and distance to river mouth were the main environmental factors influencing the riparian soil in the Taizi River Basin
