摘要
本文依据地震地质、地球物理、第四纪地质和构造地貌等资料，参照目前可以接受的应力－荷载模型、热扩散模型和非对称扩张模型，较详细地论述了江汉洞庭盆地（ＪＤＢ）的构造演化历史、主要活动断裂的新构造变形与地震活动的相关特征，尝试性地预测未来强震危险程度，并提出若干抗震防灾的对策，目的在于为ＪＤＢ的长远开发规划、生命线和重要城市的抗震减灾提供基础资料。
In this paper, tectonic evolution process, neotectonic deformation of major active faults, regional seismicity and hidden earthquake sources of the Jianghan-Dongting Basin(JDB)region are thoroughly studied on the basis of seismological,geophysical, quaternary geology and tectono-geomorphology data.By the synthesis and comparison of geological and earthquake data,it is predicted that future earthquakerisk will probably hide in the Jingmen Zhongxiang,Gongan-Songzi, Jingzhou-Honghu and Changde-Lixian areas.
