According to 23 seismic waveforms recorded by Anhui digital earthquake network , they got inelastic attenuation through Atkinson method and site response from 24 stations through Moya method. Removing effect of propagation path 、 site response and instrument response, they got 42 source parameters of earthquakes with ML≥2.0 recorded by Anhui earthquake network since 2009 using genetic algorithms method and made a systematic analysis on characteristics of it. The results show that: there is a good linear relationship between earthquake moment and local magnitude in Anhui ; there is a certain bias between the local magnitude and moment magnitude; there is a clear positive correlation between stress drop and local magnitude; the larger the magnitude is , the smaller the corner frequency is and the greater the radius of rupture is.
