摘　　要：闽江口水下三角洲的形成与演变全文从分析控制或影响闽江口水下三角洲发育的环境因素、入手，探讨了闽江口水下三角洲的地貌特征、成因及演变。研究结果表明，闽江口水下三角洲属于构造－潮控型三角洲，其地貌特征和成因与典型的潮成三角洲既有共同点，也存在着较大的差异。此外，其近期地貌的发育和演变亦受到人类工程活动的重大影响。这些结论可为闽江口航道综合整治工程提供科学理论依据。本文为其第二部分，主要探讨闽江口水下三角洲平原的地貌特征及演变。This paper discusses the geomorphological characteristics, origin and evolution of the underwater delta in Minjiang Estuary, based on the analysis of environment factors that control or affect its formation. The studied results indicated that the underwater delta in Min jiang Estuary can be classificatcd into a tectonic-tidal delta, its geomorphological characteris- tics and origin being the same with those of typical tidal delta on one hand but with larger differences on tile other. In addition, its recent geomorphological formation and evolution are significantly affected by artificial engineering. These conclusions can provide scientific basis for the synthetical harnessing project of shipping channel in the Minjiang Estuary. This pa per is the second part of the theses, which mainly discusses the geomorphological character istics and evolution of the underwater delta plain in Minjian Estuary.
