By analyzing the data of sediment observed in 11 hydrological stations in Ganjiang River, severe soil and water loss is found in Taojiang, Ganshui, Zhangshui, Pingjiang, Wujiang and Suichuanjiang, etc.The average volume of sediment in the upper reaches of Ganjiang River is larger than that in the lower reaches.Transported sediment mod ule is 144/km2 in Wan’ an statjon, 136/km ² in Ji’an station, 131/km² in Xiajiang station, 112/km² in Zhangshu station, and 114/ km ² i n Wuzhou station.The average diameter of sediment particles is 0.04 0.066 mm, and the change in sediment content is consistent with the changes of bot h the seasons of a year and rainfall or runoff.Lastly, suspended load and soil and water loss are studied, and the countermeasures are presented so as to be the basis for the further technical application in the future.
