| 中文摘要: |
| 通过塔里木河干流河道水沙资料和地形资料的对比分析，进行了塔里木河干流河道的水力几何形态、河相关系、河道稳定性和河势变化等方面的研究，指出新其满河段以上(阿拉尔至沙雅县鹿场附近河段)河势相对不稳定，属游荡型河段；新其满河段以下(新其满下游的曲毛格金至恰拉水文站)河道相对稳定，属弯曲型河段；新其满河段(沙雅县鹿场至曲毛格金)介于二者之间，属过渡性河段。塔里木河干流河道在历史上发生了很大的变化，短时间内河道除局部河势变化较大外，整体上河道仍相对稳定，1998年河势的变化范围在1978年河势活动(或滩软)范围之内。 |
| 英文摘要: |
| The morphological characteristics, stability of river stream and variation of river regime are studied base on the analysis of hydrologic and topographic data for the main stream of Tarim River. It is found that the river section upstream of Xinqiman station is relatively unstable and belongs to wandering stream.The meandering river section downstream of Xinqiman, from Qumaogejin to Qial station, is stable stream. The river section in the vicinity of Xinqiman is transitional stream. Significant change of river regime took place in the history, but it will be relatively stable in the near future. The change of river regime in 1998 is within the range of change in 1978. |
