Through the analysis of co-seismic responses features of Wenchuan M8.0 and Japan M9.0 earthquakes, we discussed the earthquake reflecting ability of the Jiangsu Fluid Observation Well Pattern System which had been digitized reformed and the reason of the major difference of earthquake reflecting ability of well holes at different measuring points. The result indicated that： （ 1 ） The co-seismic responding ability of water level was stronger than that of water temperature in regional well holes in Jiangsu. The water-level co-seismic responses had a con- sistent change law, and were closely related to the magnitude. The co-seismic responses of water temperature were great different at different well points, which were manifested as a slow restorative change. （2） There was difference of co-seismic responding ability at different well holes in different tectonic units. The co-seismic re- sponse change in central and northern Jiangsu area was weaker than that in southern Jiangsu area, whose reason is the tectonic characteristics of the thicker upper loess covering layer in central Jiangsu was weaker than the hilly country in southern Jiangsu in capturing the micro-changes of stress-strain states. The relatively complicated geo- logical structure in southern Jiangsu became more favorable to the change of underground water state by the tiny disturbance.
