湖泊湿地生态系统植硅体指示古环境研究进展

Research progress of Phytosilicon applied to Paleoenvironment in lake wetland ecosystem

湖泊湿地生态系统中植硅体由于可以有效储存流域植被信息、反映流域气候变化过程、流域碳循环以及沉积物年代测定,从而得到了广泛的研究与应用。综述了近年来植硅体在古气候、古环境研究中的应用,并进一步简述了植硅体在年代测定和化学元素分析研究上的应用进展与实例,提出当前湖泊湿地植硅体研究中存在的问题及研究展望,为植硅体在湖泊湿地生态系统重建古环境、环境考古等领域提供科学的证据和资料。

Phytolith in the lake wetland ecosystem has been widely studied and applied because it can effectively store the vegetation information of the basin,and reflect the basin climate change process,the basin carbon cycle and the sediment dating. Therefore,this paper reviews the application of phytoliths in paleoclimate and paleoenvironment research in recent years,and further describes the application progress and examples of phytoliths in dating and chemical element analysis,and proposes current silicon wetland planting. The problems and research prospects in the research provide scientific evidence and information for the phytoliths in the reconstruction of the paleoenvironment and environmental archaeology of the lake wetland ecosystem.
