近30年来我国湖泊沉积研究的进展

总结了近30年来中国湖泊沉积研究的状况。70～80年代中期，受油田开发的带动湖泊沉积研究得以兴起，且侧重研究地质过程；80年代中期之后，研究的范围不断扩大，方法不断完善，测年手段更趋精确．目前该领域研究的新特点为：云贵高原和青藏高原湖泊又成为新热点，强化短时间尺度研究，注重提取与人类活动相关的环境信息及与其他相关热点研究相结合．今后该领域研究应注意：(1)加强环境指标与环境要素间的定量关系研究；(2)强化研究人类活动对湖泊的影响机制；(3)建立中国第四纪湖泊数据库；(4)涉足极地地区研究。

THE RESEARCH PROGRESS OF LAKE SEDIMENTS OF CHINA FOR THE PAST THIRTY REARS

The article summarized the research of lake sediments of China for the past thirty years.From the 1970s to mid 1980s,the research had been developed by the tapping of oilfields mainly on geological process.Since mid 1980s,the research regions have been gradually increased,the methods of research have been well developed,and the techniques of dating have become more precise.The new characteristics of the recent research show that lakes located in Yunnan- Guizhou Plateau and Qinghai-Tibet Plateau become new hot spots,the time scale of research becomes short,and particular attention is paid on the effections caused by human activities,combining with other relative research realms.As to the further research,we should enhance the quantitative study of the relationships between the environmental index and elements,analyse the impact of human activity,set up Quaternary data base of the lakes in China,and set foot in polar lakes.
