中文摘要:利用舟山北部海域2009年完成的高分辨率单道地震测量成果,结合前人调查资料和邻近的上海长江三角洲陆地地区水文地质资料,对地震资料进行了解译和综合分析研究,查明了海底第四纪松散沉积物分布规律,初步圈定了早更新世时期的长江古河道和钱塘江古河道位置。结果揭示在调查区西部钱塘江口北侧、嵊泗列岛和“嵊泗二井”以北、嵊泗东北部海域第四纪松散层发育,所圈定的早更新世古河道分布区可能是海底淡水资源丰富区,为舟山北部海域海底淡水资源进一步调查指明了方向,为海底淡水资源开发提供了科学依据。

Primary Study on Submarine Freshwater Resources in North Zhoushan Sea Area
NameInstitution
Abstract:Based on data from high resolution single channel seismic surveys in 2009, former investigation data and neighboring terrestrial hydrogeological data at the Yangtze River delta of Shanghai, writers interpreted, analyzed and studied all seismic data synthetically. Distributing feature of submarine Quaternary sediment was found out. Locations of paleo river channels of Yangtze River and Qiantang River during the early Pleistocene were probed primarily. The study has revealed that at north of Qiantang River mouth, west to survey area, north Shengsi archipelago and No.2 Shengsi well, and northeast sea area of Shengsi, the Quaternary stratum is very thick, the predicted distribution areas of paleo river channel in early Pleistocene are possible abundant areas of marine freshwater resources. These data and conclusions may be helpful in further investigation of submarine freshwater resources and lay scientific basis on submarine freshwater sources exploitation at north Zhoushan sea area.
