摘　　要：以区域地质构造为基础，选取汶川地震前后（2006～2009年）为研究时段，重点分析了安徽省地震学参数扫描与短临前兆异常之间的协调性特征。研究表明，在小震活动发育、控震断裂集中、前兆测项位置敏感的六安-合肥地区地震学参数与前兆异常存在较好的协调关系。On the basic of regional geological structure, selected the time Pre and Post the Wenchuan Earthquake （2006 - 2009） as study period ,emphatically analyzed the coordination character between the seismological parameters scanning and short-impending precursor anomaly in Anhui area. It can be concluded that there exist better coordination relationship between the seismological parameters Scanning and short-impending precursor anomaly in Lu ＇an-Hefei area with developmental small earthquakes activity, concentrative controlled earthquake faults and sensitive precursor observation position.
