The cause research of flood along the Yangtze River is a long knotty problem of science. According to the present research, four physical factors causing flood along the Yangtze River are summed up as follows: atmospheric factor; factor of earth's surface; factor of earth's physics; astronomical factor. On the basis of emphasizing comprehensive function of physical factor, three leading factors causing large flood along the Yangtze River are analyzed, and the concept of flood cause chain is put forward. Finally comprehensive com
