中国湖泊与环境演变研究的回顾与展望

我国70～80年代中期,湖泊沉积研究受油田开发的带动而得以兴起;80年代中期之后,科研力量不断壮大,研究的内容侧重气候变化,研究区域不断扩大,方法不断完善,测年手段更趋精确;近几年来又特别注重研究云贵高原和青藏高原的湖泊,强化短时间尺度研究,注重人为因素对湖泊沉积环境的影响。今后该领域研究应注意加强环境指标的综合运用与定量化研究,强化分析环境演变中人为因素的影响,尽快建立中国第四纪湖泊数据库,积极开展极地地区湖泊的相关研究。

A Review and Prospect of Lake and Environmental Evolution in China

Based on lots of documentations, it can be said that the research of lake and environmental evolution in China had been developed by the tapping of oilfields from the 1970s to mid 1980s Since mid 1980s, much progress has been made, the power of research has been strengthened,and more attention has been paid to climatic changes. 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 particular attention is paid to the lakes located in Yunnan Guizhou Plateau and Qinghai Tibet Plateau , the research for short time scale becomes more important, and more work about the effect caused by human activities is done As to the further research, we should enhance the full utilization and quantitative study of the environmental indexes, and the analysis of the impacts coming from human activities also should be strengthened. It is necessary to set up Quaternary data base of the lakes in China to shorten the way with other countries.
