长江口海域地质灾害研究

根据地矿部上海海洋地质调查局1973年以来，在东海及长江口海域进行的大量地球物理调查、海洋地质及石油地质调查的基础上，收集了解其他单位所做成果，对长江口海域的地质灾害开展专项研究，结合海域环境地质、工程地质条件，进行综合分析，以了解和查明海域存在的地质灾害类型、规模、分布、特征等，为海域地质灾害的防御和减灾提出对策，为长江口海域、上海浦东及东海油气田的开发建设提供决策依据。

Research on the geological hazard in the sea area of the Yangtze River Mouth

Based on a great deal of geophysical, marine geological and pterolic geological investigations in the sea area of Yantze River Mouth and Eastern Sea by the Shanghai Oceanic Geological Investigate Bureau since 1973 ,this paper also gathered informations of other institutions and analyzed synthetically on the geological hazard in the sea area of the Yantze River Mouth combined with the marine environmental geology and the condition of the geological egineering to find out the type , the scale , the distribution and the characters of the geological hazard. The results could be the reference of the policy of the recovery and reduction of the marine geological hazard and the suggestion of the exploitation in the sea area in the Yangtze River, Poudong Area in Shanghai and the exploitation of the petroleum and gas in the East Ocean.
