Fract altheory was used to rebuild the embed special dimension serials based on the statistical data of flood and drought damage occurred in Anhui Province from 1949.the time serials was discussed and the fractal dimension was computed. the results indicate that time serials of the flood and drought area has fractal fea-ture. the st able fract al dimension is 2. 56 and 3.55. the corresponding minimize dimension of the st able relativeon-ship is 8.0. Hurst analysis results indicate that the areas of flood and drought are due to rapidly increase after 1980. the result can provide a base research to build the forecast model of the flood and drought damaged area.
