Abstract:: Daily precipitation data from 659 meteorological observation stations were used to calculate the interannual and decadal heavy rainfall and heavy rainfall days in China. Then, based on China’s climate change regionalization (1961—2010), heavy rainfall in China was analyzed. The results show that in the increasing and decreasing trend of total precipitation fall in the region climate change regionalization in China, most of the heavy rainfall rendered the corresponding interannual and decadal increasing and decreasing trend. But there are also decreasing trend in total precipitation in I₁ temperature fluctuation increasing, precipitation fluctuation decreasing of Xiaoxinganling—Changbaishan Montain—Sanjiang Plain of Northeast China—North China warm-dry trend zone and Ⅲ₃ temperature fluctuation increasing, precipitation fluctuation increasing of Yunnan—Guizhou Plateau—Western Nanling Mountain—Hills of Southwest China—South China dry-warm trend zone and, whereas heavy rainfall shows increasing trend; on the contrary increasing trend in total precipitation fall in Ⅳ₁ temperature fluctuation increasing, precipitation fluctuation increasing of Southeast Tibet Mountain—Plateau of Southeast Tibet—Southwest China wet-warm trend zone, whereas heavy rainfall shows decreasing trend. The similar conclusions can be drawn under the short duration and long duration of heavy rainfall. It shows that the existing primary and secondary climate change regionalization (1961—2010) reflect the changes of heavy rainfall to a certain extent. But it still need to use extreme precipitation as an indicator of the three divisions of the China’s climate change regionalization (1961—2010) to analyze the heavy rainfall in China.
