The recent progresses in researches on extreme precipitation over China are reviewed from the aspects of the thresholds， characteristics of variations， possible affecting factors， and simulation. The results indicate that recently the definitions of the thresholds are already clear and definite， and the longterm changes of extreme precipitation have obvious regional characteristics. Because the precipitation in China is affected by the various members of the East Asian climate system and the formation mechanisms are very complicated， the researches on the causes are not thorough enough. There are still some uncertainties in the simulation and estimation with the related application models.
