Using an olympic project as the paper analyzes various waveform features in the seismic imaging profiles , which are relevant to different backfills and geologic bodies in complex neritic backfilled areas , a prospecting example 并通过奥运工程勘察实例详细分析了该方法在复杂的浅海人工回填区域中不同的填入物与地质体在时间剖面上所展现的各种不同波形特征。

2 microzooplankton of jiaozhou bay were composed chiefly of neritic warm - temperate and estuarine low - salinity species . eurythermic and euryhaline species were sparse . cold - water , oceanic hypersaline and tropical warm - water species were not found during the study period 2 、胶州湾小型浮游动物以暖温带近岸、河口低盐种为主，广温广盐种较少，尚未发现冷水种、外海高盐种和热带暖水种。

These geomorphic units of paleogeography constitute the basic model of paleocontinent , littoral - neritic sea and carbonate plateform at that stage , and this depositional model is similar to the pattern of the east china continent and ocean , which is the result of evolution during the past long geologic age 这些古地理地貌单元构成了湖北省泥盆纪时期古陆滨浅海和碳酸盐岩台地的基本沉积模式，这种沉积模式与现今中国东海大陆、海洋格局基本一致，亦是经过了漫长地质历史时期演化，而形成现今这种格局的。

Results as following : in the east china sea and the yellow sea , zooplankton showed higher diversity in the low latitude and warm species occurred mainly in the south of 31 n , five communities were distinguished by twinspan method , based on data of species composition and environmental factors . they are : i ) yellow sea neritic community ( f ) with indicator species of labidocera euchaeta in autumn and centropages mcmurrichi in spring ; ii ) yellow sea central community ( hc ) with indicator species of themisto gracilipes , calanus sinicus and euphausia pacifica , the latter two species occurred only in autumn ; iii ) east china sea continental shelf mixed water community ( k ) with indicator species such as rhincalanus cornutus and pterosagitta draco which were confined in waters with high temperature and salinity , iv ) yellow sea and east china sea mixed water community ( he ) and v ) east china sea inshore mixed water community ( m ) 根据twinspan等多元分析结果，比较各组群的浮游动物种类组成和环境特征，可将东、黄海浮游动物群落分为5个，黄海沿岸群落（ f ） ，指示种秋季为真刺唇角水蚤，春季为墨氏胸刺水蚤；黄海中部群落（ hc ） ，指示种以细长脚虫戎为主，秋季还有中华哲水蚤和太平洋磷虾；东海外陆架高温高盐群落（ k ） ，指示种为角锚哲水蚤、飞龙翼箭虫等多种狭布型暖水种类；黄东海交汇区群落（ he ）和东海近岸混合群落（ m ） ，两群落包含多种生态类型种类，其中温带近岸低盐种在he中较多，广布性暖水种在m群落中较多。

Based on available data , the study on regional structure , sedimentary reservoir and source rock characteristics shows that the basins in south china sea had experienced sedimentary evolution in faulting period and depression period , deposited thick cenozoic formation , upwardly developed alluvial fan facies , river - lake facies coastal swamp facies coastal facies , neritic facies and bathyal deposit system , regionally had 3 source rocks of eocene , oligocene and miocene , 3 reservoirs of pre - cenozoic basement buried bill , oligocene sandstone and miocene reef , with pliocene and pleistocene neritic facies and bathyal shale as regional caprock 摘要以现有资料为基础，通过对区域构造、沉积储层、烃源岩特征等基础石油地质条件研究，认为南海海域各盆地经历了断陷期和坳陷期沉积演化，沉积了巨厚的新生代地层，自下而上发育了冲积扇相、河湖相、滨岸沼泽相、滨海相、浅海相、半深海相沉积体系，区域上存在始新统、渐新统和中新统3套烃源岩，前新生代基岩潜山、渐新统砂岩、中新统生物礁3套储层，区域盖层为上新统和更新统浅海半深海相泥岩。
