长江三角洲平原植被覆盖演化与人类活动的关系一直是一个争论不休的问题。本文对长江三角洲广富林新石器时代遗址的两个沉积物剖面进行了花粉鉴定和粒度分析。结合已发表的放射性碳年龄、有机元素化学和考古发现，我们重建了全新世中晚期遗址的古生态演化和人类活动，并区分了人类活动和水文过程对植被的影响。结果表明，三个事件的显着减少的丰富的乔木花粉，这发生在atc.4635，2000年，800 cal年BP，分别。前两个事件伴随着禾本科花粉的明显增加，而最后一个事件发生在一个急剧增加的丰富的紫云英科花粉。这些研究结果表明，减少乔木花粉导致砍伐森林的水稻种植的扩大atc.4635和2000卡年BP，和扩张的棕榈科油料作物。800年前。800年前耕作方式的变化与当时战争造成的中国北方人口迁移的增加是一致的。水生植物花粉在4500 cal yr BP时急剧增加，反映了长江口与海平面上升有关的水文环境变化。
There has been an ongoing debate about human impacts on the evolution of the vegetation cover on the Yangtze delta plain dating back to the Neolithic period. In this study, we carried out pollen identification and grain size analysis on two sediment profiles obtained from the Neolithic Guangfulin site in the Yangtze delta. Together with published results of radiocarbon ages, organic elemental chemistry and archaeological findings, we reconstructed the palaeoecological evolution and human activities at the site during the mid- to late Holocene and distinguished between the impacts on vegetation induced by human and hydrological processes. The results show three events of significant reduction in the abundance of arboreal pollen, which occurred atc.4635, 2000, and 800 cal yr BP, respectively. The first two events were accompanied by an obvious increase in Poaceae pollen, whereas the last one occurred with a sharp increase in the abundance of Brassicaceae pollen. These findings suggest that the reductions in arboreal pollen resulted from deforestation for the expansion of rice cultivation atc.4635 and 2000 cal yr BP, and expansion of Brassicaceous oil cropsc.800 years ago. The change in cultivation patternc.800 years ago was consistent with the increase in population migration from northern China caused by war at that time. The pollen of aquatic plants increased sharply atc.4500 cal yr BP, which reflected the change in hydrological environment related to sea-level rise at the Yangtze River mouth.
