摘  要：
通过对赣江河流泥沙变化量的观测与分析,跟踪寻找出水土流失严重的河流为桃江、贡水、章水、平江、乌江、遂川江。11个观测站点多年观测结果表明,赣江多年平均输沙模数上游最大,上游各河均>140 t/km~2。赣江干流多年平均输沙模数自赣州市至南昌市,由上而下逐次变小,万安站144 t/km~2,吉安站136 t/km~2,峡江站131 t/km~2,樟树站112 t/km~2,外洲站114 t/km~2。赣江河流泥沙颗粒多年平均值,各河大都在0.04～0.066 mm之间。赣江流域输沙量年内分布规律表现为与降水量、径流量年内分配一致;此外,对水土流失状况、原因、发展态势进行了分析并提出了防治对策。

摘  要：
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 rea- ches.Transported sediment module is 144/km~2 in Wan'an station,136/km~2 in Ji'an station,131/km~2 in Xia- jiang station,112/km~2 in Zhangshu station,and 114/km~2 in Wuzhou station.The average diameter of sedi- ment particles is 0.04～0.066 mm,and the change in sediment content is consistent with the changes of both 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.
