摘　　要：根据浅地层地震剖面的解译结果,对南黄海西部滨浅海区灾害地质要素进行了识别。结果表明,研究区存在多种灾害地质要素,包括海岸侵蚀与淤积、水下浅滩、浅层气、埋藏古河道和古三角洲、沙脊、陡坡、沙层液化、冲蚀沟槽、滑坡、差异性压实断层等等。探讨了灾害地质要素的特征和分布规律,并绘制了主要灾害地质要素分布图。Marine geo-hazard factors in the western South Yellow Sea were studied based on seismic profiles.There are different types of factors which may cause geo-hazards in the study area,such as coastal erosion and siltation,submarine shoaling,shallow gases,buried paleo-channels and paleo-delta,sand ridges,steep slope,soil liquefaction,submarine deep scour channel,landslide,faults caused by differential compaction,and so on.The characters and distribution of geo-hazard factors were described and discussed based on the distribution map of main marine hazard factors we compiled.
