| 摘 要： | 通过对现代塔里木河干流河道大断面的泥沙堆积情况、河道的基本特征和上游来水来沙条件的研究，认为塔里木河河道冲淤较大，主槽摆动频繁；涨水时低滩地淤积，落水时冲刷；每经一个汛期，滩面有所抬高；长时期内滩槽相对高差变化不大；河道淤积量大小主要取决于上游来沙、来水量，尤其是汛期水沙量对河道变迁的意义重大

INVESTIGATING INTO THE VARIATOIN OF EROSION AND SILTATION ON THE MODERN CHANNEL OF TARIM RIVER |
| |
| Abstract: | Investigating into the cross section, siltation, water flow and silt content of main Tarim river course proved that the erosion and siltation of the river channel varied largely and the main course wandered frequently. The depositional variation mainly depended on the capacity of water and silt from the upper river, especially in flood period. In details, the lower beach was deposited during flooding period and eroded in dry season. But, the average height from the river bed to the beach had no more change in the last years. |
