三角洲

The rate of subsidence has been decreasing from area near vertex of delta to the coastal zone and some place is even rising, particularly in the early formed area. What is the different in the coastal is that the rate of subsidence is still high and can sustain a long time. This is because the land subsidence in the delta is mainly caused by the consolidation of sediments if there is no human activity. Especially in the newly formed area, Qingshuigou sub-delta, the rate of subsidence was more than 50 mm/a in the begining and now is still higher than 10 mm/a. When the newly sediments discharged by the Yellow River landed on the subaquatic delta, its load can drive the concolidation of the silt, which is on the surface of the Bohai seafloor. The rate of consolidation of the silt will be decreasing quickly in the first years, but still a long time in the later time with a slow rate.

研究结果表明：现代黄河三角洲在以宁海为顶点的河口扇形区域，近期均经历了不同程度的地表下沉过程，但是随区域地理位置和时间的不同，地表变化空间差异性比较明显；三角洲顶点附近区域的下沉速率自上世纪末开始逐渐减小，后期甚至出现轻微的抬升；滨海沿岸附近地区的地表形变特征相对比较复杂，各期叶瓣相互叠置及其各类沉积物的不均匀分配，使由沉积物自然固结压实引起的地表形变具有显著的空间差异；目前，除清水沟流路叶瓣表现为快速沉降以外，其它滨海沿岸区基本上都表现为微弱的下沉。

Because of the differences of the faults in active time and position, nearshore subaqueous fans are disjunctive on the plane and overlapped in vertical with the fan deltas.

受断层活动期次和横向活动差异的影响，近岸水下扇具有在平面上与扇三角洲间互出现，剖面上与扇三角洲相互叠置的特点。

Developers want to transform nearly 20,000 hectares of the spectacular Tana River Delta, into sugarcane plantations with other parts of the Delta earmarked for rice.

In order to know physical properties of Eogene reservoir origin type in Gudong area clearly,the physical properties of the main reservoir origin types were studied in detail including sandbodies of braided-river delta, meandering-river delta, shallow lake and bathyal lake.

为详细了解孤东地区古近系储层成因类型的物性特征，分别对其主要的储层成因类型———辫状河三角洲砂体、曲流河三角洲砂体、浅湖砂体和半深湖砂体的物性做了详细研究。

The results showed that the temporal-spatial distribution pattern did not alter basically from May 2002 to May 2006, and the topsoil congregative type of soil salinity profiles was the majority in the Yellow River Delta, which indicated that the risk of soil salinization was great, and the level of amelioration and rational utilization for saline soils needed to be improved further in the Yellow River Delta.

结果表明：从2002年到2006年，该地区土壤盐分剖面类型的空间分布格局基本没有改变，黄河三角洲土壤盐分剖面类型总体以表聚型为主，这表明黄河三角洲土壤盐渍化风险大，必须进一步提高盐渍土的治理和合理利用水平。

Its mission is to acquire the knowledge needed for sustainable living and working in low-lying deltaic areas, with a focus on hydraulic and geotechnical engineering, geosciences and the integrated management of surface and groundwater and aquatic ecosystems.

沃润德教授作为荷兰皇家科学院生态学会三角洲分会的主任，该分会主要是探讨低洼三角洲地区的可持续生态需求，侧重于水文和地理技术工程，地球科学及地表水和水文系统的综合管理研究。

The study shows that the advantageous sandstones in the area have the following distribution characteristics: in the environment of growth faults, sandstones are mainly distributed in the downthrown block of a boundary fault; in a lowstand systems tract, sandstones are mainly distributed in lowstand wedges, slope fans, basin-floor fans, fan deltas, deltas and submarine canyons; in a transgressive systems tract, sandstones are mainly distributed in sandbars and sand-beaches; and in a highstand systems tract, sandstones are mainly distributed in deltas, fan deltas and submarine fans.

并指出有利砂体的分布特征：低水位体系域，砂体主要分布在低水位楔、斜坡扇和盆底扇；高水位体系域，主要分布在三角洲、扇三角洲、海底扇和峡谷水道。研究表明，以层序地层学理论为指导，划分层序和体系域，进而对有利砂体进行预测，对该地区油气勘探有重要指导意义。
