摘要
通过大量文献资料 ,总结了近 3 0年来中国湖泊与环境演变研究的状况。 2 0世纪 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年代中期以后 ,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。目前该领域研究的新特点表现为 :注重研究云贵高原和青藏高原湖泊 ,加强短时间尺度研究 ,注重人为因素对湖泊沉积环境的影响。今后研究方向为 :①加强环境指标与环境要素间的定量关系研究 ;②加强分析人为因素对环境演变的影响 ;③加强高分辨率湖泊沉积与环境演变的整体、长序列研究 。
The authors used a lot of data to have summarized lake and environmental evolutions in China since the last three decades.During 1970s and 1980s,the lacustrine sedimentary researches uprose due to the development of oil fields.And in mid 1980s,more attention was paid to climatic changes,and as a result of that,the research range expanded,methods were improved,and dating techniques more precise.At present,the researches are highlighted on lakes in the Yunnan-Guizhou Plateau and Qinghai-Tibet Plateau,on short-time scale evolution,and on influences of human activities on the lacustrine sedimentary environments.In the future studies,we will put emphasis upon the quantitative relation betweenthe environmental indices and elements,influences of human activities on the environments and high-resolution and long-sequence studies of lacustrine sedimentation and environmental processes to establish the lake data base.
