通过对洞庭湖区自然地理环境中湖区变迁、地貌反差特征、第四系沉积厚度、地貌发育过程、地质环境改变与地震活动关系进行了讨论。湖区东岸的岳阳一带虽具有湖区变迁,但地貌反差不显著,历史和近代地震活动显示,未来地震活动存在相对减弱的趋势。湖区西侧的澧县至常德一线具有湖区变迁、地貌反差大与地貌发育等特征,地震会相对活跃,无论是历史地震,还是近代地震活动水平都相对较高。为了防止中强地震的突然袭击,必须加强对该区的地震活动监测和科学研究工作。

The area of Dongting and geological environment and Lake changes, geomorphological the relationship between seismic ment of the lake are discussed in the paper. The results are that weak seismic activity, while in the western lake area from contrast, the thickness of Quaternary deposits activity and the natural geographical environ- the eastern lake area near Yueyang city shows Changde to Lixian appeared relatively high level of seismicity, therefore we should strengthen our earthquake monitoring and scientific research in this area.
