摘　　要：通过对2007年3月13日福建顺昌M_L4.9、4.7地震序列、震源机制解、地震烈度等震线、地震地质及发震构造、震中附近地壳P波速度结构等资料分析,结果发现:地震序列具有孤立型地震序列特征;郑坊断裂(f_2)为本次地震的发震构造;北东东向的南平一宁化断裂带应作为福建省主要地震构造给予重视;顺昌一南平一带未来存在发生中强地震的可能。Through analyzing the data of Fujian Shunchang ML 4. 9, 4. 7 earthquakes on March 13, 2007, which of seismic sequence analysis, the focal mechanism solution, isoseismal of seismic intensity, seismogeology and seismogenic structure analysis, P-wave velocity structure around the epicentre, we can generally conclude that： firstly, sequence indicates the characteristic of isolated seismic sequence. Secondly, the seismogenic structure is Zhengfang （f2） fault. Thirdly, Nanping-Ninghua fault zone should be valued as the main seismotectonics of Fujian. Finally, the moderately strong earthquake may occur in Shunchang-Nanping area in the future.
