摘要:
根据现场调查和室内分析,北仑河口动力地貌有剥蚀丘陵、残丘、冲积平原、冲积-海积平原、海积平原、沙堤、沙滩、淤泥滩、红树林滩、河口沙坝、潮流沙脊、潮沟及人工地貌。北仑河口经历全新世早期侵剥蚀形成古河道,全新世中期海水浸入古河道,形成河口湾;全新世中-晚期河口湾被充填,形成湾内沙坝;全新世晚期河口湾逐渐被填满,形成现代北仑河口动力地貌态势。

Abstract:
The chief mprpholedcal typies in the Beilun river estuary in China terriory are denuded hills, remanent hills, alluvial pain, alluvial-marine plain, marine plain, sand bar, sand flat, mud flat, mangrove beach, river mouth bar, tidal sand ridge, tidal ditch and artificial morphology, according to the data of spot investigation and information analysis. The Beilun river estuary were denuded and formed palaeo-river course from pre-Holocene to early-Holocene, invaded by seawater and bestuary during the mid-Holocene, progressively developed a modern dynamic morphological state in the late-Holocene.
Key words:  Beilun river estuary  dynamic morphology  evolutional process
