摘要
黄河口尾闾的变化是由黄河口海岸侵蚀机制与堆积机制共同作用的结果。利用遥感技术对河口尾闾进行监测,可直观反映调水调沙对河口段河道冲淤变化的影响程度,也是调水调沙试验在河口影响的平面形态的最好展现。结果表明:调水调沙期间,河口口门附近不管是河道延伸,还是造陆面积都有不同程度的增加;调水调沙对河口的冲淤平衡有重大的作用。
The variation of the sink of the Yellow River estuary is the outcome of combined action of erosion and deposition mechanisms of the river estuary.Monitoring the sink of the estuary by utilizing remote sensing technique can not only directly show the effects of scouring-erosion variation of the channel at estuary section through a regulated discharge regime of the river,but also is the best presentation of the test influence to the estuary in plane.The outcomes show that not only the channel near the outlet has been extended,but also the created land area increased to varying degrees during the tests of a regulated discharge regime of the river and;a regulated discharge regime has significant roles on keeping the balance of erosion and deposition of the estuary.
