摘　　要：选取福建地震台网"十五"观测系统正式运行以来记录的2009—2012年的M L≥2.0级地震事件,根据断裂构造特征和地震的空间分布情况,将研究区域划分为3个地区。采用多台和达法计算波速比研究了福建地区的波速比和泊松比分布情况,并且讨论了2012年4月15日福建仙游M L4.1级地震前后的波速比变化特征。In this paper, based on the ML ≥ 2. 0 earthquakes which were recorded by the seismic observation network of Fujian province from 2009 to 2012, and according to the condition of the fracture characteristics and the space distribution of the earthquakes, the research area is divided into three parts. The distribution of the wave velocity ratio and Poisson＇ s ratio in Fujian is studied by the multi-station Wadati method, and dis- cussed the varied characteristics of the wave velocity ratio in Xianyou ML4. 1 earthquake.
