Abstract

Flood damage leads to great economical loss. Based on precipitation data at Huzhou and Yixing which are located in the upper area of Taihu Lake, precipitation distribution in different seasons and its tendency have been analyzed. The result shows that the precipitation in flood season is about 60% of the annual total amount in most of years during 1997-2002, and 35% in summer and 15% in winter respectively. The tendency analysis suggests that precipitation has been indecreasing in flood season. Slight drought prevailed in this area before 1974 and then flood and drought ocurred alternatively. The conclusion also shows that El-Nino or La-Nina occurred in most of the disaster years. Spectrum analysis is also conducted with the result that the significant period is about 20 years and the sub-period are 2.2 and 3.3 years. The anti-correlation between rainfall and sunspot is also revealed. From the conclusion, the prediction is given that the prevailing damage will be drought in the coming 20 years with possibility that heavy flood disaster will occur due to abnormal climate.
