【 摘 要 】

Extreme weather events will change the current situation and distribution of the water cycle in the region, resulting in reallocation of time-space distribution of water resources, and directly affect precipitation, and runoff. In recent 20 years, it has experienced drought for three consecutive years from 2009 to 2011 in Kunming, in addition, serious urban waterlogging happened in almost every year which cause by the extreme precipitation events, this article selects 1998-2011 monitoring stations in kunming. The time, frequency and variation characteristics of rainstorm are studied. Through the study we found the formation of storm floods of factors in addition to natural factors, the change of the underlying surface conditions of urban waterlogging has played a more important role.
