The strong area rainfall in the six drainage areas of the upper reaches of Changjiang River from 1971 to 2000 is statistically analyzed.Through the relationships of the frequency, extremum distribution, running extremum with the strong precipitation among the six drainage areas, the spatial temporal distribution characteristics are given. It is shown that there is the obvious seasonality, distinct annual variation, obvious differences in heavy area rainfall frequency distribution, ordering distribution, extremum distribution, precipitation intensity among six drainage areas, and close relationships between border drainage areas.
