The Significance of the Research on the Environment Evolution from the Lakes of Monsoon Region in the Historical Period

本文首先讨论了历史时期季风区湖泊环境演化研究在古全球变化研究中的地位及其意义，着重强调加强人与自然相互作用研究以及进行定量研究是该领域的关键所在．综合中国近年来在湖泊沉积与古全球变化研究中取得的成果，提出在该领域研究的一些新的认识与亟待解决的问题．

This paper has firstly discussed the significance of the research on the environment evolution from the lakes of monsoon region in the historical period. in which the quantitative reconstruction of the proxies and the study on the human interaction with the nature have been treated as the key points In this field. The authors have also put forward some questions which should be paid much more attention and be solved in the field of palaeolimnology and past global change study, e. g. the energy and moisture interrelation in the different monsoon rigion under a glacial/interglacial cycle, the cold climate event in the past climate etc and how to distinguish the human impact on the lake records.The past studies have shown that the southwest monsoon region was generally characterized by cold-wet climate in the Post-Glacial and warm-dry climate in Holocene,whereas the southeast monsoon region, dry in Post-Glacial and wet in Holocene. In addition, a series of cold climate events did exist since the post-Glacial. The authors have provided some preliminary analysis on these phenomena. As for the study on the human interaction with the nature, the author suggest that the change in the proxies caused by the human activitles must be recognized and correspondingly, the relation between the palaeoenvironment change and human activities need to be cleared out. This will helpful for the reasonable utilization of lake resource in the future.
