Abstract: According to <Earthquake Cases in China>, which introduced 188 earthquake (M_S≥5.0) cases occurred from 1966～1999 in China's continent, among which, 126 earthquake cases are related to the fluid anomaly and there are 803 fluid anomalies, their time-space characteristics are statistically analyzed based on the appearance and diversion of anomalies and earthquake generation with the changes of time and the anomaly amount with the changes of the epicentral distance. The results show that: no matter what the trend or short-term anomaly is, in the different time stage, the amount of the anomaly has obvious stage feature, the special distribution of the anomaly changes with the distance of the epicenter. And the consistence of them in time-space distribution is founded in the study of each earthquake case and different districts.

Key words: Earthquake cases in China, Fluid anomaly, Statistical analysis
