基于大凌河流域自然状况及社会经济状况，选取上窝堡、朝阳、义县、凌海等4个主要水文站实测资料统计流域特征，分析大凌河输水输沙能力，同时结合流量与输沙率变化关系图、主槽平均面积比较表、各河段主槽宽度多年变化关系图、各河段不同时期的主槽容量表，从输水输沙能力和横纵向冲淤变化的角度上分析大凌河河床形态。结果显示：大凌河的河口以凌海为顶点，先向南再向北发展，体现出反复摆动的特征；河道平滩河槽和枯水河槽的过流能力由上游到下游沿程逐步增加；河道主槽的宽度反复变化，趋于逐渐变窄，主槽面积逐年递减。

Based on the natural conditions and socio-economic status of the Daling River Basin ,this paper selects the measured data of four major hydrological stations ,namely the Nest Fort ,Chaoyang ,Yixian ,Linghai ,to get the basin characteristics ,and has an a‐nalysis of the water and sediment transport capacity of Daling River .Meanwhile ,combined with the flow change and transport rate graph ,the average area of the main channel comparison table ,the width of the main channel of each reach variation diagram ,the main channel capacity of each reach in different periods'table ,this paper analyzes the riverbed morphology of Daling River from the perspective of the water and sediment transport capacity and the vertical and horizontal changes of erosion and deposition .The re‐sults show that the estuary of Daling Rriver ,starting with Linghai as the vertex ,develops towards the south first and then to the north ,reflecting the characteristics of repeated swinging ;the conveyance capacity of the bankfull channel and the low flow channel of the river course gradually increases from the upstream to the downstream along the way ;the width of the main channel of the river course repeatedly changes ,tending to narrow gradually ;the main channel area is diminishing year by year .
