根据厦门湾-九龙江口地区3个钻孔的孢粉组合特征分析，结合沉积相和年代数据，探讨本区晚更新世以来的古气候和古环境演变。孢粉分析结果表明，MIS4阶段早期以来该区的古气候演变包括：晚更新世偏冷干-早中全新世（约8～5.5 cal. ka BP）温干转热湿-晚中全新世（约5.5～2.5 cal．ka BP）较暖湿转温和稍干-晚全新世（约2.5 cal．ka BP至今）暖湿等的波动和变化。晚更新世全球范围的大幅降温在本区影响较大，全新世气候变化的特点是温湿度在一定幅度中波动，人类活动对植被的干扰在晚全新世以来有明显的体现。

According to pollen assemblage analysis of 3 boreholes in Xiamen Bay-Jiulong River Estuary region,combined with the results of sedimentary facies and dating analysis,this paper explore the paleo-climatic and paleoenvironmental evolution in this area since Late Pleistocene.Pollen analysis show that:since the early stage of MIS4,the main paleoclimatic evolution of the region includes the fluctuations and changes such as:slightly dry-cold in Late Pleistocene,dry-warm then wet-warm in early Mid Holocene (8~5.5 cal.ka BP),wet-warm then slightly moderate-dry climate in late Mid Holocene (5.5 ~2.5 cal.ka BP)and wet-warm in Late Holocene (since 2.5 cal.ka BP).Global scale substantial cooling e-vent in Late Pleistocene impacts clearly in this area.Characteristic of the climate change in Holocene is that the temperature and humidity varies fluctualy between some ranges.The human activity infects clear-ly the vegetation form since Late Holocene.
