| 摘 要： | 河流中的离子输移与泥沙运动有着密切的关系,通过对流域侵蚀过程中物理化学作用分析指出,流域的离子溶出与流域泥沙侵蚀过程具有伴随性,相应的泥沙和离子输移也具有相关性.通过研究嘉陵江和渭河干流站点的离子输移与泥沙输移的实测资料得出,河流离子输移量与泥沙输移量具有明显的正相关关系.河流中不同种类的离子输移与泥沙输移的相关程度不同,不同河流二者相关关系存在着一定的差异.

| Abstract: | There exists the mutual influence of ions and sediment in river water.And the sediment discharge and the ion chemical character are linked together.In this paper,the progress of the physical and chemical denudation in a river basin is analyzed,and the relat ionship between ions and sediment is researched according to the data obtained at the hydrological station on Jialing River and Weihe River.The result indicates that the positive relationship between the sediment discharge and ions discharge is evident,the related coefficient changes if the ions.category changes,and the relationship is different in the different river. |
