通过资料收集和整理,对湖南深部地球物理场布格重力异常、航磁异常、莫霍面、地热场和地壳结构反映出来的特征进行了总结和分析,同时对湖南历史地震（Ms≥434级）和近代地震（ML≥3.0级）与这些深部地球物理场特征的关系进行了讨论。结果表明：湖南地震活动的空间分布与深部地球物理场特征有一定的内在关联,有较好的对应关系。
通過資料收集和整理,對湖南深部地毬物理場佈格重力異常、航磁異常、莫霍麵、地熱場和地殼結構反映齣來的特徵進行瞭總結和分析,同時對湖南歷史地震（Ms≥434級）和近代地震（ML≥3.0級）與這些深部地毬物理場特徵的關繫進行瞭討論。結果錶明：湖南地震活動的空間分佈與深部地毬物理場特徵有一定的內在關聯,有較好的對應關繫。

In this paper,the authors summarized and analyzed the features reflected by Bouguer gravity anomaly,aeromagnetic anomaly,Moho surface,geothermal field and crustal structure in Hunan deep geophysical field based on the collected data.And the relationship between the historical Ms≥43 4 earthquakes and recent ML≥3.0 earthquakes and these characteristics of deep geophysical field were discussed.The results show that there are certain internal connection and good corresponding relationship between the spatial distribution of seismic activity and deep geophysical features in Hunan area.
