Outlier test is used to ensure that raw data is a statistical real and effective. We then derived relationships between I and each ground-motion parameter by using a weighted least squares regression to fit a log-linear function, considering appropriate increase the weight in high intensity area and decrease the weight in low intensity area. The analysis results show that for peak acceleration with Ⅴ≤I≤Ⅸ, logPGA=0.268I+0.330, and for peak velocity with Ⅴ≤ I≤Ⅸ , logPGV=0.277I-0.753. The statistic results indicate that PGA values of this paper is as about 1.3 times as that of the Chinese seismic intensity scale(CSIS2008) models with Ⅴ≤ I≤Ⅸ , meanwhile, PGV values of this paper is as about 1.24 times as CSIS2008 models with Ⅴ≤ I≤ⅨCompared . to the corresponding values in the ShakeMap system, the results of this paper are lower. It indicated that he CSIS2008 models, however, are conservative to earthquake hazard assessment and seismic design in China.
