摘　　要：本文以新编《江西省区域地质志》总结的地质构造新成果为基础,结合江西省地震局提供的地震记录,对江西省新构造格局、地震活动特点和动力机制进行研究。结果表明,江西省地震震中分布与新构造格局密切相关,地震活动主要发生在北北东向的幕阜山—罗霄山地震活动带和怀玉山—武夷山—九连山地震活动带的南部。进一步理清了江西省主要的破坏性发震断裂和主要发震地区的构造环境,为优化地震区划、地震监测和防震工作提供依据。Based on the latest research results of geological structures in 'Regional Geology in Jiangxi Province',and earthquake records provided by Seismic Administration of Jiangxi Province,this study analyzes neotectonic framework,seismic activity characteristics and dynamic mechanism in Jiangxi Province.The result shows that the distribution of epicenters in Jiangxi is related to the neotectonic framework,with seismic activities occurring mainly in the NNE-trending Mufushan-Luoxiaoshan seismic active belt and the southern part of the Huaiyushan-Wuyishan-Jiulianshan seismic active belt.Main destructive seismic faults and tectonic environment of seismogenic zones in Jiangxi have been further clarified,which can provide important basis for optimizing seismic zoning,seismic monitoring and earthquake prevention.
