地球化学指标在黄土环境演变研究中的应用进展

The Application and Progress of Geochemical Indicators in the Study of Loess Environmental Evolution

中国黄土沉积纪录了最近2.6Ma以来黄土高原及全球自然环境演变的历史。重建其演变历史以预测未来气候环境的变化趋势是指导该地区经济、生态环境建设的重要基础。黄土的地球化学指标是重建该地区环境演变历史的重要途径之一。基于进一步研究的目的,总结了黄土地球化学指标在环境演变研究中的应用和近年来取得的进展。

Loess deposition in China has recorded the histories of the environmental evolution in the Loess Plateau and other areas of the world since the recent 2.6 Ma. It is very important to reconstruct the history of environmental evolution for forecasting the climatic changing trend and to guide economical construction and environmental restoration in these areas. Loess geochemical indicator is an important way to recon- struct the history qf climate-environment evolution. Based on the purpose of further study, the paper tries to sum the application and progress of loess geochemical indicators in the study of environmental evolution＇ in recent years.
