In this paper，we overlaid the Seismic Ground Motion Parameter Zonation Map and Potential Seismic Source Zone Map on the basis of the county borders in the National Significant Seismic Monitoring and Protection Regions，and analyzed the distribution of 4 seismic parameters among these counties: (1) the largest PGA ( Peak Ground Acceleration) in each county，(2 ) the PGA which occupies the maximum areas in each county，( 3 ) the highest Mu ( upper limit earthquake magnitude) level in each county，and (4) the Mu which occupies the maximum areas in each county． The result shows that although these counties all belong to the National Significant Seismic Monitoring and Protection Regions，they have various seismic diversities． Based on this knowledge，we finally give recommendations to administrate the seismic risk in category in the National Significant Seismic Monitoring and Protection Regions．
