Abstract：Based on the historical flood data in Daye Lake Basin during the year of 1901－2000， the temporal characteristics and disaster grade were analyzed. And the periodic change law and characteristics of flood disaster grade were analyzed by the Matlab wavelet analysis method. The result shows： the flood disasters of Daye Lake Basin occurred in the lower frequency in the early stage and more frequently in the late， with seasonal and significant concentration which mainly concentrated in the summer. Severe flood disasters were primary in the middle and late period， and moderate flood disaster and catastrophic flood disasters were frequently. The periodic changes and laws of flood disasters in various grades were very different. Finally， the causes and counter measures about the flood disaster in the Daye Lake Basin are brought forward.
