采用震源位置及速度结果的联合反演方法确定闽粤赣交界区(24o~26.5oN，114o~117.8oE)地震的震源位置以及震源区速度结构。结果显示：①闽粤赣交界区地震震源平均深度随震级增大而加深的特征明显，即地震震级越大，震源深度越深，但平均深度不超过15 km；越靠近沿海，地震震源深度有加深的趋势。②通过对河源地区、邵武-河源断裂带中段(寻乌-瑞金)区域、政和-大浦断裂带中段(漳平附近)区域以及闽粤近海区域地震剖面研究，发现地震多发生于高低速异常结合部位。

The paper uses the joint inversion method to determine the hypocenter location and velocity structure of Fujian, Guangdong and Jiangxi border zone (24o-26.5oN, 114o-117.8oE) . The results show that: ① the characteristics of the average depth of hypocenter in Fujian, Guangdong and Jiangxi border zone deepened with magnitude increases with the average depth not more than 15km, that is to say, the larger the earthquake magnitude, the deeper the focal depth, meanwhile, closer to the coast, earthquake focal depth deepen;②based on the studying of the seismic profile of Heyuan area, the middle (Xunwu-Ruijin) region of Shaowu-Heyuan fault zone, the middle region of Zhenghe-Dafu fault ( Zhangping nearby) and the offshore areas of Fujian and Guangdong, the author finds that the earthquakes often occurred in the binding site of the high and low speed anomaly.
