摘要
介绍了天山西部河流水系的概况,对水文站点的实测泥沙资料进行了分析,结果表明:天山西部河流的输沙量在年内主要集中在4—8月,其年内集中度比径流量的大,受区域气候及人类活动的影响,河流含沙量呈增长趋势;天山西部河流干流段泥沙级配存在细—粗—细的变化过程,说明区间支流及沿河岸崩岸侵蚀的泥沙对泥沙粒径的沿程变化产生了一定影响。
This paper introduced the general situation of rivers system on the western Tianshan Mountains and analyzed the observed sediment data of hydrological stations. The results show that the sediment discharge in the west Tianshan Mountain rivers is mainly concentrated from April to Au-gust,the concentration is larger than runoff in a year,river sediment concentration presents a growing trend affected by regional climate and human activities;the sediment gradation of the western Tianshan Mountain rivers main stream presents the change process from thin to thick then to thin, explains that interval tributary and the banks alone the rivers erosion of sediment have an impact on sediment grain size change.
