| 摘 要： | 根据太子河河岸带69个样点的土壤分层调查, 研究了太子河河岸带土壤特征、空间格局及与环境因子的关系。研究结果表明:垂直剖面自上而下土壤含水率、土壤孔隙率、总磷、有机质和总氮含量显著减少, 容重、pH和有效磷在层间差异不显著。根据土壤理化性质, 将样点分为2类, 一类主要分布在太子河上游及某些支流上游, 该类土壤呈弱酸性, 有机质和总氮含量高, 另一类主要分布在太子河中下游, 该类土壤呈弱碱性, 有机质和总氮含量较低。利用冗余分析(RDA)识别影响土壤性质的环境因子, 结果表明海拔、年降水、年均温和距离河口的距离是影响土壤空间差异的主导因子。

| Abstract: | 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 |
