Abstract:

In this paper，the flood disaster data of China's major river basins，which include the Zhujiang River，the Changjiang River, the Huanghe River，the Huaihe River, the Hailuanhe River，the Liaohe River and the Songhua River, were analyzed. The relationship between sunspot activity，solar eclipse，EL Nino events and flood was explored. The results shows that: when the sunspot number is less than 27 and more than 105，then prone to floods，especially the occurrence of big floods and super flood; when an EL Nino event occurs in three years，the frequency of occurrence of flooding disasters is very high; floods year is no eclipse occurs and the emergence of multiple solar eclipse.

Key words: flooding disasters, sunspot, solar eclipse, EL Nino, corresponding analytical method
