Abstract : qidong field is characterized by different structures from deeper to shallower strata , its main pay bed is fluvial sandstone segmented by deep cutting faults 文摘:歧东构造带具有浅层与深层构造相异的特征，主要产层是断层分割的河流相砂体。
Glacier recession has more palpable repercussions in china including water resources dearth , frequent floods , wetland degradation and fluvial systems fragility 在中国，冰山的退化所产生的影响日趋明显，其中包括水资源短缺、水患频发、湿地退化和河流系统稳定性降低等。
In oil field of china , fluvial and delta facies reservoir are main depositional facies type , and their geological reserve accounting for nearly 80 % of total reserve of clastic rock facies 中国油田河流相与三角洲相储层的地质储量占碎屑岩相总储量的近80 ，是主要的沉积相类型。
The last , the author analysise the character of plain and section with interpretation of logging , then obtain the fluvial sandbody architecture influenced to charaters of reservoir 最后，利用解释成果计算分析了储层平剖特征，并分析了砂体内部建筑结构对储层内部性质的影响。
The fluvial sediments of the neogene in the nanpu 35 - 2 area of central bohai gulf are well - developed and can be divided into two types as meandering river sediments and braided river sediments 摘要渤海湾中部南堡35 - 2地区新三系河流沈积十分发育，可分?曲流可沈积和辫状河沈积两种类型。
And the fluvial genetic unit includes point bar , the bottom of channel , bursted fan , bursted channel , natural bank , over - bank deposits , small lake of flooding plain and swamp and so on 成因相包括点坝、河道底部沉积、决口扇及决口河道、天然堤及越岸沉积、泛滥平原小型湖及沼泽等。
These nine environmental changes were well reflected by the variations of coarseness and fineness of grain - size of fluvial sedimentary profiles near dongweiqiao site of tang dynasty . 3 这不仅在剖面各层的粒度累计含量可以清楚地反映出来，且各个粒度参数一md 、 mz 、 o 、 sk和kg也同样具有显著响应。
The sedimentary systems were alluvial fan - braided fluvial river - lacustrine depositional systems during the paleocene - eocene , and braided fluvial river - lacustrine depositional systems during the oligocene - miocene 古新世始新世发育冲积扇辫状河湖泊沉积体系，渐新世中新世发育辫状河湖泊沉积体系。
The weser estuary in germany , with broad beaches , lots of sand bars and many tributaries , is characterized with a great quantity of sediment transport due to tidal current ' s movement in the fluvial bed of fine sediment 摘要德国威悉河口滩地宽广，有无数的沙洲和许多大的分流，潮流在主要为细沙的冲积河床中运动，泥沙输移量极大。
The ongoing fluvial , marine and aeolian processes in the site have produced a variety of landforms , including coral reefs , long sandy beaches , coastal dunes , lake systems , swamps , and extensive reed and papyrus wetlands 不断的河流，海洋和风的侵蚀作用使得该地呈现多样地貌，包括珊瑚礁、漫长的沙滩、海岸沙丘、湖泊、沼泽、大片的芦苇丛和纸草沼泽。
