摘要
研究了辽河口三角洲前缘岸滩近50a来的演变特征,结果表明,在流域来水来沙减少的背景下,海域浅滩迎浪面普遍侵蚀后退,双台子河口拦门沙北偏东移,向口内发展,西滩滩外坡持续侵蚀,海域-2m、-5m等深线附近海床整体呈弱冲刷态势,近岸潮间带岸滩整体变化不大,相对平衡。结果可以为辽河口近岸工程建设和资源开发提供决策依据。
The evolution characteristics of delta forward coastal at Liaohe estuary in the past five decades is in studied this paper.The results are as follows： due to the decrease of the riverine sediment supply,basin,the head sea side of the shoals in the sea waters generally eroded,and the mouth bar of Shuangtaizi estuary shifted to north east,moving to the internal river mouth.Xitan tidal flat also keeps the erosion trend,and the seabed presents overall weak erosion state,but the nearshore tidal flat variations were small,relatively balanced.The studies could be a decision-making foundation for the coastal engineering and resource development at Liaohe estuary.
