摘　　要：分析了安徽地震前兆台网三大学科观测项目的现状,统计了近年来安徽前兆观测数据的同震效应与映震情况,结果表明:仅局限于地表或浅层的前兆观测数据,很大程度上难以获取到反映地震孕震过程的真实有用信息。提高现有前兆数据使用效率、选择真正有意义的前兆观测手段和直接触及孕震区边界的观测敏感点是安徽地震前兆台网的发展方向。We analyze the current situation of the three main items of Anhui Precursory Observational Network such as earth deformation,geomagnetism,and underground fluid,and study the coseismic effect and anomalous response of the data yielded by the Network in recent years.We find that it is difficult to obtain the true abnormal information of seismogenesis on the surface or in the shallow crust of the Earth.Therefore,It is urgent to enhance Anhui Precursory Observation Network by improving efficacy of the observational data,choosing effective precursory items,and selecting sensitive points in the earthquake-pregnant body.
