摘要:
研究全新世以来的气候变化特征,是当今世界范围内古气候研究的重点和热点。位于亚洲东南部的中国西南地区,地貌类型复杂,其气候变化不仅受全球性气候因素驱动,也显著受其它区域性因素的影响,更加具有复杂性。在对中国西南地区全新世以来孢粉重建古气候相关研究整合分析的基础上,归纳总结了该区百年时间尺度上全新世植被演替和气候变化的主要特征。主要通过综述西南地区典型地理单元全新世以来的气候演替特征,进而围绕区域性和全球性的气候突变事件进行了比较研究,结果表明:西南地区全新世以来总体呈现湿润的气候特征,即早期(11.5~8 ka BP)气候从干冷向暖湿转变,中期(8~3.5 ka BP)温暖湿润,晚期(3.5 ka BP至今)气候向减湿方向发展;该区气候对于8.2ka冷事件的响应不如5.5ka冷事件明显,表明该区具有相对独特的区域性气候特征。最后鉴于西南地区全新世古气候研究相对滞后的现状,对未来需要着重加强的工作提出了建议。(图4 参53)
Abstract:
Due to present-day global change, a considerable effort has been made over the last few decades to provide reliable estimates of paleoclimate changes, particularly since the Holocene. Southwestern China with complex geomorphic types was located in southwestern Asia. Its climate is not only driven by global climate factors but also significantly affected by other regional factors. To infer past climate changes that occurred in southwestern China and to better understand the mechanisms that drive those changes, we analysis the vegetation succession and climatic changes in southwestern China based on palynological reconstructions and paleoclimate studies since the Holocene. The collections of regional pollen databases and several well-dated sequences offer exceptional opportunities to investigate the temperature and rainfall distributions and their variations through time and space in southwestern China during the Holocene. Correspondingly, the results revealed that the climatic change in southwestern China can be classified into three stages. The initial stage was from 11.5 to 8 ka BP, during which the climate changed from cold-dry to warm-humid. The second stage (8~3.5 ka BP) was characterized by a relatively warm and humid climate. In the late Holocene (since 3.5 ka BP to present), the climate and environment began to become increasingly arid. The consistent climate fluctuations in southwestern China were identical to those of global climate changes. Notably, the climate of southwestern China response more obviously to 5.5ka cold event than 8.2ka cold event, indicating a typical regional climate characteristic. Further quantitative reconstruction of the Holocene climate in southwestern China should provide more detailed data on the local and even regional climatic changes.
