摘要：

通过对中国图们江河口湖沼沉积剖面的植硅体组合的分析，划分出该剖面自17.1～2.247 kaB.P.期间的６个植硅体组合带，分别对应冷干-凉湿-冷干-凉湿-温暖-温湿的气候阶段。将分析结果与本剖面Na、K、Ba、Cu、Pb、Fe、Mn分析相对比，发现植硅体对气候湿润程度的反映不如Na、K、Fe敏感，但是比其它指标，如泥炭地发育程度对湿润度的反映，要灵敏得多。区域对比发现，本剖面的植硅体古气候过程存在着区域上的良好响应，对全球变化与区域响应研究起着积极作用。

Abstract:

According to the analysis on the phytolith of the swamp profile in Tumen River estuary, the phytolith assemblages can be divided into six zones, which are corresponding to the paleo-climate phases of “cold and dry-cool and wet-cold and dry-cool and wet-warm-moderate and humidity”. Comparison between the phytolith analysis results and the results from Na, K, Ba, Cu, Pb, Fe and Mn analysis of this profile shows that the phytolith is not as sensitive as elements such as Na, K and Fe on the humidity reflection, but it is more sensitive than the reflection of peat development to the humidity. Regional paleo-climate contrast indicates that phytolith paleo-climate process of the profile under study has a good response to the regional climate evolution and will play an active role in the global changes and regional responses research.

Key words: phytolith, paleoclimate changes, swamp sediments, Tumen River estuary
