Abstract

The flood affected area (FA) dataset was built up for the whole country and main flood provinces in China from 1950 to 2005; then flood disaster variations and future flood patterns were investigated with the help of complexity measurement method and Mann-Kendall test. Possible relationship with climate change for flood change and future patterns in China are also discussed. Some meaningful results are obtained as follows. The average FA and its complexity increased very fast in the 1980s and 1990s for the whole country and the upward trend of rainfall intensity and extreme precipitation in the late 20th century may be an important reason for the magnification of flood disasters. As for provinces, the study reveals regional character of future's FA trend. The future pattern of flood disasters embodies the characteristics of 'flood in the south and drought in the north' and 'flood intensification to the west of Hu Huanyong's line'.
