| 摘 要： | 研究湘江江水悬浮态和溶解态金属浓度的变化、重金属在沉积物中的赋存形态及对制约湘江江水重金属进入沉积物的地球化学作用结果表明,在湿热的湘江流域气候环境条件下,河流水体中重金属的地球化学作用一方面表现出明显的地带性特征,即Fe/Mn水合氧化物的吸附沉淀作用较强,又受区域地质条件、岩石性质的影响,表现为较强的碳酸盐的地球化学作用,但不同金属的地球化学趋向不同,铅易以碳酸盐形式、铜主要依靠有机质的结合作用进入沉积物。

| Abstract: | The behavior and the fate of heavy metals in Xiangjiang River were controlled by both zonal climatic conditions and geologic formation. The scavenging action of ferro-manganese oxide was related to the hot and damp climate and the precipitation of the metals as carbonates, on the other hand, was mainly due to the rock character of the area. Different metals went to sediments through different pathways. |

| Keywords: | heavy metal ferro-manganese oxide carbonate Xingjing River |
