Mainly using 612 earthquake events of M_L≥2.0 recorded by Shanxi network digitalized in “the tenth-five year plan,” use the China seismological bureau earthquake prediction research institute promotion of small and medium-sized earthquake new parameter calculation software，this paper calculates new source parameters of 148 events, makes a primary research on scaling relation among parameters of seismic moment, moment magnitude, source fracture scale, stress drop, corner frequency etc., concludes that M_L magnitude has well linear positive correlation with seismic moment and moment magnitude; polynomial relationship with source scale; obviously positive correlation with the logarithm of stress drop, which will be released a little more slowly with the increase of the magnitude if M_L≥4.0; negative correlation with the logarithm of corner frequency. There doesn’t show significant relationship between stress drop and source scale, but from here we can have more thoughts, giving new theoretical explanation of two controversial earthquake events.
