中文摘要	通过定量分析浙闽地区三个典型剖面(浙江象山石浦、松阳枊城下湖源及福建武夷山崇安)的暗色岩系沉积期的孢粉化石,研究了早白垩纪浙闽地区的古气侯特征。研究表明,石浦地区孢粉中Pinuspollenites,Podocarpidites,Celtispollenites 和Ulmuspollenites含量最多,下湖源地区孢粉以Pinuspollenites,Gleicheiniiidites,Classopollis和Deltoidospora为主,崇安地区孢粉以Classopollis,Tracheid,Pinuspollenites和Podocarpidites为主。孢粉化石组合表明,石浦地区为亚热带潮湿气候,气候变化较小;下湖源地区为亚热带潮湿-半潮湿气候,并出现一次变热变干事件;崇安地区为亚热带半干旱气候,但发生过数次干旱与潮湿交替的气候波动。总体而言,早白垩纪研究区属于亚热带气候,具有潮湿、干旱交替变化、自东而西越来越干旱的特征。
英文摘要	By quantitative analysis of spores and pollen from early Cretaceous dark mudstones from three typical sections in Zhejiang and Fujian provinces, paleoclimate features of this area were obtained. Primary analysis of fossil spores and pollen shows that Pinuspollenites, Podocarpidites, Celtispollenites, Ulmuspollenites are characterized in Shipu section, Pinuspollenites, Gleicheiniiidites,Classopollis, Deltoidospora in Xiahuyuan section, Classopollis, Tracheid, Pinuspollenites, Podocarpidites in Chong’an section.Quantitative analysis of fossil spores and pollen shows that there has been a humid subtropical climate with less climatic fluctuation in Shipu, a humid-half humid subtropical climate with a short term of hot and dry climate in Xiahuyuan, half dry subtropical climate with apafleeowc ltiimmaetse owfithu nsdevuleartailo unsndbueltatwieoenns bheatlwf-eaerind haalnf-darihda laf-nhdu hmaildf-hcluimmiadt eanidn itC’sh omnogr·’ea na.n dI nm ocroen cdlruosuigohnt, ftrhoims estaustd tyo iwnfeesrt.s a subtropical paleoclimate with several undulations between half-arid and half-humid and it’s more and more drought from east to west.
