根据长江三角洲地区全新世９个具代表性钻孔的孢粉分析结果讨论了本区约自１２０００年以来的环境变迁。孢粉序列表明：本区约在距今１２０００年前就已发育了亚热带性质的落叶常绿阔叶林，约在９０００—５０００ａＢ．Ｐ．常绿阔叶林获得大发展。孢粉序列良好地记录了古季风盛衰的历史，表现在：１２０００—１０８００ａＢ．Ｐ．较温湿，东南季风强度加强；１０８００（或１１０００－１００００（或１０３００）ａＢ．Ｐ．偏闵干，东南季风强度减弱，对应于新仙女木期；约自１００００ａ．Ｐ．起，气候好转，气温明显上升，东南季风强度再次增强，约在９０００—５０００ａＢ．Ｐ．温暖湿润，为东南季风强盛期。此外．还讨论了约在距今１１０００年前的海侵，全新世下限和哥德堡事件的年代问题，并确定哥德堡事件的年限为１１０００—１０００ａＢ。Ｐ。
Based on the results of sporopollen analysis of 9 representative boreholes in the Holocene in the Yangtze River Delta, the environmental change in this area since about 12000 years has been discussed. The sequence of sporopollen indicated that the deciduous evergreen broad-leaved forest with subtropical nature has developed about 12000 years ago in this area, about 9000-5000aB. P. Evergreen broad-leaved forest gets big development. The sporopollen well recorded the history of the ancient monsoon rising and falling, manifested in: 12000-10800aB. P. Relatively warm and humid, easterly monsoon intensification; 10800 (or 11000-10000 (or 10300) aB.P. Partial dry, southeast monsoon intensity weakened, corresponding to the new fairy woody period; from about 10000a.P., the climate has improved, The temperature rose significantly, and the intensity of southeastern monsoon strengthened again, about 9000-5000aB.P., warm and humid, which was the southeast monsoon. In addition, the transgression, Holocene lower limit and Gothenburg event about 11000 years ago were also discussed The issue of age, and to determine the duration of Gothenburg incident 11000-1000aB.P.
