摘要/Abstract

摘要： 塔里木河流域的水文特性在过去几十年内发生了深刻变化，源流的年径流总体增加，而干流发生量级洪水的频次与洪峰流量也有显著增长，干流防洪压力不断增长。通过从洪水传播时间、削峰率、耗水率三个方面对塔里木河干流上游（肖夹克-英巴扎）分河段展开系统分析，揭示了干流上游洪水传播的一般规律；在此基础上构建了一维水沙演进的数学模型，模型通过2010年洪水验证后，模拟了2017年干流洪水演进过程，模拟结果精度较高，显示了该数学模型的合理性和广阔的应用前景。研究成果不但从科学上揭示了中亚代表性内陆多沙河流的洪水特性，对于塔里木河干流的防洪管理与洪水资源化利用也有重要意义。

Abstract: The hydrological characteristics of Tarim River Basin,Xinjiang,China have undergone profound changes in the past decades.The annual runoff of the origin increased while the frequency and the peak discharge of magnitude floods in the main stream increased significantly,which lead to the increase of flood protection pressure.In 2001,the Tarim River ecological rescue project was implemented,and the recent governance project of the Tarim River main stream was carried out after 2002.After the boundary conditions and water and sediment conditions changed significantly,there is still a lack of quantitative analysis and research on the flood travel time and peak-clipping rate of the mainstream Tarim River.This paper systematically analyzed flood characteristics in the upper reach of the mainstream of the Tarim River (Xiaojiake-Yingbazha reach) from three aspects:Flood travel time,peak-clipping rate and water consumption rate,which revealed the general law of flood transmission in the upper reaches of the main stream.The travel time of peak flood is concentrated in 1.5-5 d from Aral to Xinqiman,and the average peak-clipping rate is 24%.The travel time of peak flood is concentrated in 2-10 d from Xinqiman to Yingbazha,and the average peak-clipping rate is 50%.The water consumption rates are 36%-56% at Aral-Xinqiman reach and Xinqiman-Yingbazha reach in June and July.In August and September,the water consumption rates of the two reaches are gathered in 23%-28%.A one-dimensional mathematical model of water and sediment evolution is constructed.After the verification period using flood events in 2010,the model simulated the main stream flood evolution process in 2017 and the simulation results with high accuracy was obtained when the flow peak of Aral exceeds 800 m³·s^-1,which indicated the rationality and wide application prospect of the model.The results of this study have scientifically revealed the flood characteristics of the representative inland sandy rivers in Central Asia,and have important significance for flood-control management and flood-water resources utilization of the Tarim River.
