It is thought that the channel bay line evolution processes can be divided into four stages. The first stage is soon of the sea level stable when the bayhead mountines are eroded and developed abrasion geomorphy and the productive materials were transport into the bay deposition by the tidal current and wave current and were reworked into gravel dams. The second stage is characterized by the fluvial output sediments and eroded sediments mixed deposition in channel bay and developed marine accumulation plain and sand riges in the plain under the wave reworked. The third stage developed clay silt marine accumulation plain under the action of the channel current and the wave action is very limited. The fourth stage is marked by human being reclaim which result in the channel bay filled and evoluted into a strait arce coast.
文章认为,峡道海湾的充填经历了四个阶段,第一阶段以峡道海湾湾顶山体在波浪作用下产生的侵蚀物质充填为主,发育了海蚀崖、海蚀洞、海蚀穴等侵蚀地形和湾顶砂砾石堤等堆积地形交替的峡道湾顶地貌,第二阶段以河流输出物质和峡道湾岛屿、礁石侵蚀物质在潮流作用下向峡道湾输运,由潮流和波流共同沉积为特征,发育海积平原,部分粗颗粒泥沙在波浪的改造峡,发育平原沙堤,第三阶段以河流输出物质为主,在涨落潮流搬运下进入峡道和峡道湾沉积,在峡道湾中发育以淤泥质粉砂为主要物质的海积平原,第四阶段以人类围涂造田为标志,加速峡道湾的充填过程,使峡道海湾最终趋于夷平,形成顺直均衡的弧形海岸。
