中文摘要：

通过对“嵊泗二井”地层层序和孢粉层序分析结果与前人研究成果及数据进行对比，同时参考长江三角洲、东海内陆架的第四纪沉积环境演化的总体框架，对嵊泗二井进行了第四纪地层的划分，并初步探讨了各含水层和隔水层的地层特征，为今后对东海陆架区地下水的开采和利用提供研究基础。

英文摘要：

Under the total framework of the sediment environment evolution on the Changjiang Delta and inner - shelf in the East China Sea during the Quaternary Period, the Quaternary stratum of Well ShengsiII were identified on the basis of the stratigraphic sequence and palynologcal stratigraphy, as well as the correla tion with provious data and results. The characteristics of the aquifer and water - proof stratum recorded in Well Shengsi II were discussed primaryly. The results rich the basic data for the water exploitation in the shelf of the East China Sea in future.
