摘    要:广州番禺东涌剖面样品的AMS(磁谱仪)年龄及红树林孢粉分析结果表明,珠江三角洲存在晚更新世和全新世的红树林,红树林是海侵的标志之一.按照检出红树属花粉的9个剖面的分布以及5处埋藏红树林腐木的分布,可以描绘出全新世海侵的边界.根据东涌剖面的沉积旋回、样品年龄、红树林花粉含量曲线、半咸水-淡水硅藻及热性-温性硅藻含量曲线的综合分析,可将沉积环境的变迁分为4个阶段.第一阶段和第三阶段的海侵有利于红树林的发展,第二阶段不利于红树林的发展,第四阶段的晚全新世,红树林的生长频繁,显示人为因素的影响.

关 键 词:海洋地质学  红树林  孢粉  硅藻  环境变迁  晚第四纪  珠江三角洲

Abstract:The depositional environment of the Pearl River Delta in the Late Quaternary and the spatio-temporal change in the climate are discussed on the basis of serial sampling and the results of sporo-pollen analysis of mangroves and accelerator mass spectrometry dating of samples.The profile of Dongchong in Panyu,Guangzhou is taken as a representative and associated with correlative profiles.The research results show that there were mangroves during the Late Pleistocene and Holocene in the Pearl River Delta.The m...
