摘要
闽江河口区处于中亚热带向南亚热带的过渡地带,自然环境演变复杂。本文着重研究其晚更新世以来的海陆变迁与气候变化,讨论其3次海进、2次高海面以及全球气候-海面变化对它的影响。
Based on the analysis of micropaleotological assemblages and chronostratigraphy, this paper discusses sea transgressions, variation of sea level and climatic changes in the Minjiang Estuary, Fujian since the Late Pleistocene.
There were three transgressions in this region during that period: Langqi Transgression at about 65ka,B. P. ;Fuzhou Transgression at about 30ka, B. P. and Changle Transgression during 13k—2ka, B. P.. In the Holocene during 6k—7ka,B. P. and 3k-4ka,B. P. the sea level was twice higher than it is now and because of the balance depression caused by deposition, the relative sea level in the later period seemed higher than it was in the former one.
The climatic changes and the development of vegetation in this region are largely under the influence of the world climatic changes and had a good relation with the sea level variation.
