     Based on the Catalogue of Chinese Historical Strong Earthquakes （23rd century B.C.to 1911 A.D.） published in 1995,we first analyzed statistically the overall distribution of the numbers of intensity points of Chinese historical strong earthquakes,then in time,geographical distribution and magnitude respectively.The results show that：the number of intensity points of Chinese Historical Strong Earthquakes are generally small.In time and magnitude,before 1500 A.D.,due to the conditions,many historical earthquakes were not recorded or were not passed down,yet those handed down only have limited intensity points.Because the records were too simple and incomplete,the largest earthquake which was evaluated was less than Ms7.0 in B.C.Earthquakes with Ms ≥ 8.0 were recorded only after 1500 A.D.In geographical distribution,historical earthquakes intensity points in eastern China are obviously more plentiful than western China.We focally analyzed the earthquakes with only one intensity point,and used historical seismic parameters acquisition method on modem events with both instrument records and macro investigation records to discuss the impact of scare intensity points on earthquake parameters＇ determination.
