淤泥滩

The deep water deposition means the deposition in the area where the water depth is larger than 30 meters, in which the major sediments are coarse sand and gravel. This kind of deposition is the relic deposition formed by the Pleistocene alluvial-lacustine deposition reworked under modern channel currents actions, and ususally the Holocene acummulation lack in the deep waters. The transitional zone deposition is the deposition between the low tidal level line and the 30 meters isobath, where the sediment types is changeable and the grain sizes are gradually coarsening from the low tidal line to the deep water area. This kind of deposition is developed by the deep water eroded sediments sorting under the transitional zone current action. The different types distributed along the isobath. The tidal flat deposition is the fine sediment deposition on the tidal flat which is flo sedimentation of the silty clay under the tidal flat dynamic action and ususally developed fluid mud on the lower tidal flat. The channel mouth deposition is the deposition in the channel mouth area. According to the sediment types, it includes sand deposition where there are coarse sediments supply and silt deposition where there are only fine sediments surpport.

峡道深水区沉积是指水深大于30米的峡道底部沉积，它以粗颗粒砂砾石沉积为特色，是现代峡道水动力对第四纪海退时发育的冲洪积和坡积物进行改造形成的蚀余沉积，全新世沉积地层往往缺失；峡道过渡带沉积是指水深介于低潮位线至30米水深线之间发育的峡道边坡沉积，该带沉积以沉积物类型多样为特色，自低潮位线至30米水深线，沉积物粒级逐渐变粗，由粉砂质粘土逐渐递变为中粗砂，是峡道深水区沉积物经多次分选沉积而发育的，基本平行于等深线分布的条带状沉积，在岸坡较陡岸段，过渡带下部可发育重力沉积；峡道潮滩沉积是指在低潮线与海岸线之间发育的细颗粒沉积，它是粘性细颗粒泥沙在潮滩动力作用下，发生动水絮凝沉积而形成的粉砂质粘土沉积，在低潮滩可发育浮泥；峡道口门区沉积则是在峡道汇入大海或海湾时，在峡道出口水流影响所及范围的沉积，根据峡道口门区供给泥沙的特性，峡道口门区沉积有粉砂质淤泥沉积和砂质沉积两种类型。

Mudflats and estuarine silts are fine substrates rich in organic matter and low in oxygen.

淤泥滩和江河入海口处的淤泥是很细的基质，富含有机物质和低的含氧量。

For example, the polyploid rice-grass Spartina townsendii is better adapted than either of its parent species to their own habitat of saline marsh and mud-flats.

例如，多倍体唐氏米草比其父本、母本更能适应父母本自己的盐碱沼泽和淤泥滩栖息地。

The tidal flat along Bohai Gulf extends from Haihe River Mouth to Dakou River. According to the results of field survey, the inter-tidal flat has obvious zonation. From the shore seawards, 4 zones can be identified, and they are depression polygon, inner depositional, erosional and outer depositional zones, and the associated sediment types are mud and clayey mud, mud, alternating laminae of silt and mud, and coarse silt, respectively.

渤海湾潮滩海岸从海河口以南到黄河三角洲北缘的大口河以北，据野外调查发现，这里的潮间浅滩具有明显的分带性，从岸向海可以分为四带，即龟裂带、内淤积带、滩面冲刷带、外淤积带，相应各带的沉积物为：淤泥与粘土质淤泥、淤泥、粉砂与淤泥互层、粗粉砂。

Most of the flood from the wide inner lowland plain discharges through tide locks on coast,and the influence of tidal flat inning projects on the tide lock drainage must be solved by seawall line choice.

淤泥质海岸后方大面积的低地平原主要通过海岸上建设的涵闸排水，潮滩匡围对沿海涵闸排水的影响是围垦工程必须解决的问题。

Flood drain of wide lowland plain behind mud coast mostly clings to tide locks on seacoast,and the influence of tidal flat inning project on tide lock drainage should be solved through seawall line choosing.

淤泥质海岸后方大面积的低地平原主要通过海岸上建设的涵闸排水，潮滩匡围对沿海涵闸排水的影响是围垦工程必须解决的问题。

Coast zone, located in the connection belt of sea and land, has been becoming an important area for the international competition and exploitation owing to itself abundant natural resources and predominant geographic location. Silt tidal flat and suspended sediment of case II waters are two important research issues.

海岸带地处海陆之交，它凭借其自身丰富的自然资源和优越的地理位置成为国际竞争和开发的重要区域，淤泥质潮滩和Ⅱ类水体悬浮泥沙是其重要的研究对象。

As a sensitive belt of sea and land interaction, silt tidal flat is characterized as muddy surfaces, densely covered and frequently varied inlets. Therefore, the routine topography survey method has been greatly restrained.

淤泥质潮滩作为海陆相互作用的敏感地带，滩面泥泞、潮沟密布、变化频繁，常规的地形测量难度极大。

For the modern river bed, River floodplain alluvial gravel soil, sand, silt deposition, thick 5-10 m.
