【摘要】 从不同时间尺度、空间尺度及与其他研究结果的对比等方面总结了近年来淮河流域湖泊沉积与环境变迁研究的主要成果.目前相关研究主要集中在洪泽湖、南四湖、高邮湖等几个面积较大的湖泊.已有的湖泊沉积记录主要以短时间尺度研究为主,而中长时间尺度研究稍显不足,这可能与该地区湖泊沉积连续性较差有关.与中国东部其他地区研究结果的对比表明,淮河流域湖泊沉积所反映的气候环境变化和其他地区具有较好的一致性.当前和今后该地区需要进一步分析更多湖泊沉积岩芯所反映的区域气候与环境变迁历史,并加强不同湖泊之间以及与其他湖泊之间的对比研究,开展不同环境代用指标与气候要素以及人类活动之间定量关系的研究,发现新的更为敏感的环境代用指标,探讨该地区历史时期古洪水的发生及演变规律,深入理解区域湖泊变化及其驱动机制.更多还原

【Abstract】 For the past years,many studies related to lake sediments and environment changes in Huaihe River Basin have been carried out.In this paper,these studies were synthesized based on various aspects of different time scales,spatial scales,and comparisons with other results.Presently,the ralated studies in the Huaihe River Basin mainly focus on several large lakes,such as Hongze Lake,Nansi Lake,and Gaoyou Lake.These records are mainly short-term in temporal scale,but it is deficient for the studies with the medium and long-term scales.This may be related to the poor continuity of lacustrine deposition in this area.From the comparison among these study results and those in other areas in eastern China,the climate and environmental changes in the Huaihe River Basin are in good agreement with other regions.Overall,many aspects must be emphasized in the current and future studies in this region.More lake sites should be explored to understand the history of regional climate and environmental changes,and the comparison among these studies as well as with other results from different regions need to be strengthened.Moreover,the quantitative study between proxies and climatic factors and anthropogenic activities should be deepened.New sensitive proxies also required to be discovered to investigate the occurrence and evolution of the paleoflood in this area,and have a better understanding of the lake changes and their driving mechanisms.更多还原
