摘要
辽河是中国七大江河之一,同时辽河也是一条多沙河流。据统计,1954—2010年系列辽河下游六间房站多年平均含沙量达3.32 kg/m3,辽河中下游的泥沙淤积是一个亟待解决的问题。为对辽河中下游水沙特点更好的研究,摸清辽河中下游泥沙冲淤演变规律,特对辽河中下游各主要支流选取一个水文站作为控制,得出了辽河来水来沙特点是东部水量大,且西辽河是辽河干流泥沙最主要的来源。
The Liao River is one of the top seven rivers in China, and also a sediment-laden river.According to the data, the average annual siltment reached 3.32kg/m3 at Liujianfang Station in the lower Liao River from 1954 to 2010.Silting in the middle and down streams of the Liao River is a problem to be solved.In order to study the characteristics of inflow and silt on the middle and downstream of Liao River and the evolvement law of siltment, selecting a hydrological station in the middle and down streams of every major branch of the Liao River as the controlling point,obtaining that eastern water is big and the westen Liao River is the most major source for the main Liao River.
